What’s your running shoe’s medical history?

 

Today’s run (treadmill): 25 minutes

When you go to a medical office for the first time, they usually present you with a clipboard loaded with forms that you have to fill out before you can see the doctor. Among those forms is a checklist for your family medical history. It makes sense since the best way to predict future health problems is to know your areas of risk. I’m applying the same concept in assessing the useful life of my main pair of running shoes.

I’ve always been skeptical about the commonly-held view that trainers should be replaced between 300 and 500 miles. Just as people may carry greater risk for certain illnesses, some shoes and brands seem predisposed to wear out sooner than others. My first pair of running shoes were some Nike Foot Locker specials that only lasted about 400 miles. But I ran in a pair of Brooks Adrenalines for 700 miles before I retired them.

People tell me that they notice when their mid-soles have worn out after a few months. I think it’s all in their head. Unless you are a large person, it’s unlikely that you would significantly compress EVA enough to matter. I’ve come to believe that it’s the out-sole that determines the life of a shoe. When I’ve needed to replace a pair, it’s usually because the wear pattern on the bottom has caused a change in my foot strike.

Of all the running shoes I’ve owned, the pair I’ve liked the most were the original Saucony Kinvaras. Unfortunately I loved them past the point where their out-sole could provide me a stable platform and I ended up with a knee problem. After 466 miles, I took them out of the rotation. I’m currently running in the Kinvara 3’s, a great shoe as well, but I’ve reached 436 miles with them. That’s only 30 miles less than what I got out of the first Kinvaras.

Saucony’s new Virrata looks interesting

So far, I’ve experienced no knee issues when running in the 3’s, but the wear patterns are starting to show. Should I be proactive and replace the 3’s in case they go from good to bad in the next 30 miles? Or should I put faith in the idea that Saucony may have engineered a more robust out-sole in the two generations since the first Kinvara? I’m on the fence about it, but it doesn’t take much to get me back into shoe-buying mode.

Running shoes: your mileage may vary

Adrenaline and Kinvara are best in the long run

Today’s run (treadmill): 25 minutes

I like running shoes for the same reason I like sports cars. They are the only layer between you and the road and they’re engineered to enable performance. If you use your imagination, sports cars and running shoes even look similar, sharing the same aerodynamic profile. The biggest difference between the two is that while anyone can go fast in a Porsche, the best thing a running shoe can do is optimize a runner’s potential.

In the 4+ years that I’ve been running, I’ve acquired a number of shoes. Some of them were great and some are best forgotten. I started logging my workouts on Daily Mile in April of 2010 and that service provides me with a tool to track the mileage of my running shoes. With the exception of the first few pairs I bought back in 2008, I have a complete history of my time spent with every shoe that I’ve owned since late 2009.

Saucony Kinvara (original)
Brooks GTS 10

I recently exported my shoe mileage data and graphed it to visualize the range (above). When people tell me that they notice their running shoes breaking down after five months, I’m usually skeptical because my Brooks Adrenaline GTS 9’s held up for more than 700 miles. My all-time favorite running shoe, the original Saucony Kinvara, performed well for almost 500 miles before giving out. I ran a little too long in those and suffered a bad knee problem due to it. Despite that, I still can’t bring myself to throw them out.

My current shoes of choice are the Kinvara 3’s for the road and, for the treadmill, the Pure Drift prototypes that I tested for Brooks. Had I requested size 11’s instead of 10.5’s for the Pure Drifts, I’d probably be wearing them more often. The fit in the toe box is just a little too narrow for my foot, so I don’t use them for long runs on pavement.

The good thing about running shoes (vs. sports cars) is that you buy new ones often without breaking the bank. I suspect, based on history, that the Kinvara 3’s will need replacement in the next few months. I’m tempted to replace them with the production version of the Pure Drift, but there are a couple of New Balance models that interest me. Plus, a whole new crop of 2013 models will soon arrive from the other brands.

While I’m thinking about it, it might be time to add a new trail shoe to my collection. Why not? It would certainly be cheaper than getting a Land Rover.

Change of pace on an Xmas morning run

Shoe of the day

Today’s run (street): 4.7 miles

Today is Christmas day and the neighborhood was quiet in the morning. We had sleet and snow overnight and the streets were shiny from the rain. I’d originally planned to go to Stillwell Woods but I didn’t feel like dealing with wet rocks and muddy trails. I figured that most people would be hanging out at home and I’d have the streets mostly to myself.

It had been a couple of days since I last ran and I hoped that the break would be energizing. Just to mix it up, I selected my Spira Stinger XLT’s that I’ve neglected for months. I dressed for the 37° weather, stepped outside and observed that the clouds had given way to sun. While my Garmin searched for a signal, I saw a familiar runner passing on the street to my left. I wanted to follow him, but the GPS was being a little too poky. A minute later I was ready to go.

The Spiras were a nice change from the Kinvaras. I love the fit and comfort of the Sauconys, but the Spiras, almost as comfortable, return a little more energy. The one criticism I have of the Stingers is that the “Wavesprings” are noticeable underfoot. I recall feeling them during the half marathon training runs that I was doing earlier in the year. These shoes are great for shorter runs, but I wouldn’t want to cover more than ten miles in them.

Like last Saturday, I was able to sustain a good level of energy throughout today’s run. I only intended to run 4 miles but I got caught up in the experience and extended my route. I don’t know how much credit I should give to the Spiras, but I covered my distance a minute faster than I thought I would. As much as I downplay performance, it’s always fun to beat expectations.

I hope to get to Stillwell or another park at some point this week. Today the streets of my neighborhood were just what I needed to get back to into my running routine. Happy holidays to all.

I run in the 2nd best shoe (umm, make that sneaker)

Best sneaker ever? Highly debatable

Today’s run (street): 3.75 miles

Prior to this week, I had never heard of The Sneaker Report. But after a few mentions by people I follow on Twitter, I checked out the site. The reason why people have been tweeting about Sneaker Report is because of a post called The 100 Best Running Sneakers of All Time. Any list that ranks people or things will be debated, and I’m sure that’s the case here. Their choice for number one is a Nike model from 1995 (Nike Air Max 95) that looks like a cross between a Skechers Resistance Runner and the shoes the Apollo 11 astronauts wore when they walked on the moon.

The original Kinvara, better than the 3

Redemption came with the choice for number two: the Saucony Kinvara 3, that happens to be my preferred running shoe right now. But as much as I like the Kinvara 3, I like the original Kinvara more, because it was groundbreaking and (in my opinion) a little more responsive. The other choices seemed odd to me and many appeared to be selected for the way they look. I shouldn’t be surprised since the site refers to running shoes as “sneakers.”

After battling pounding headaches and exhaustion earlier in the week, I’m almost back to my old self. I took it easy on the treadmill yesterday in terms of speed but I set the incline at 2% to get my heart rate up a bit. Today I planned an outside run and though the temperature on the local news station showed 41°, I bundled up with extra layers. That turned out to be a good decision because it felt far colder than low 40’s, especially when the wind was blowing. My Kinvara 3’s did little to insulate from the cold and I’m wondering if I need a winter shoe.

Since I’m not fully back to strength, I decided to keep my distance in the 3 to 4 mile range. I felt fine as I ran but, after a mile, I noticed that my legs were feeling heavy. I was running a high 9:00 pace and my heart rate was low, so I just kept moving. I can’t say I enjoyed the workout, but it wasn’t like I was suffering. Once I reached three miles I started to follow roads that headed back toward my house.

This has been a week of moderately easy running and I’m fine with that. I’ll probably target 5 or more miles tomorrow. I’m certainly not in speed or performance mode these days. After reading the WSJ.com article last Tuesday, I’m not so concerned about performance. At least I’m not this week.

Nature or nurture? Outgrowing my running shoes

A growing problem

A couple of weeks ago I gave away three pairs of running shoes to someone with same shoe size. My collection of running shoes had reached a point where I needed to store them in four different locations. When I made the exchange I had a total of 13 pairs. Now it’s down to 10. I should probably get rid of most of the rest because, remarkably, the majority of them no longer fit me.

When I finished growing (at around 19 years old) I naively assumed that I’d never need to buy clothing again. Over the years I’ve had to replace worn clothes and buy more occupationally appropriate attire, but I’d always assumed that I would fit into the same shoes forever. Four years ago I started running again and bought a pair of Nike shoes. They fit me well and I liked them.

A lot has changed since that purchase in 2008. I no longer care for Nike’s and I doubt I could even fit my foot into those shoes. It’s strange, but since I started running, my shoe size has increased a full size and a half. I started at 9.5, moved up to 10’s about a year later and, by early 2010, I needed 10.5’s. Now most 10.5’s are too tight in the toe for me to use, except on shorter runs.

The Spira’s and the Kinvara 3’s are both 11’s and they fit me well. I was still thinking I was a 10.5 when  Brooks picked me to test a pair of prototype shoes a few months back. I really like the shoes but the fit is annoyingly snug on the outside toes. Had I asked for 11’s, I’d probably be rotating these shoes with the Kinvaras on almost every run. Happily, the Saucony’s provide me with a quality running experience and I appreciate them more every day.

Outgrowing shoes gives me an opportunity to buy new ones (and as my wife would point out, a reason to get rid of old ones). I’m wondering why this has happened. Is running flattening or spreading the volume of my feet? More importantly, when does it stop!?

When testing shoes, three can be a crowd

Testing 1,2,3

Today’s run (treadmill): 2.5 miles

I’m feeling a little guilty regarding my delay in posting my reviews about the Spira Stingers and Saucony Kinvara 3’s. I have written a fair amount on both shoes through this blog, so it’s not like I haven’t reported on them. Now, with the new shoes that I am testing for the manufacturer, it’s even harder to focus on one particular brand.

I’m about halfway through my review of the Spiras, so I decided to wear them on this morning’s run. Once again, the rain forced me to stay inside on the treadmill. It was extremely humid at the start, so I moderated my pace to prevent overheating. The treadmill has dual fans that throw a decent amount of air, but that was no match for today’s heat.

After running so often in the Kinvaras, and more recently in my test shoes, I was better able to discern key differences between the three pairs. The Spiras, which I sized up by 1/2 to ensure a good fit in the toe box, are flexible at the mid-foot, but the uppers bag when the shoe flexes. I also noticed a little pressure from the wavesprings on the fore-foot, something I hadn’t experienced before.

I ended up having a decent run, though I throttled my performance in deference to the heat and humidity. As I ran through my workout, my eyes locked on the the other two pair in my current rotation. If I had to choose only one shoe, which would it be? After today, I think the answer is starting to come to me.

I’ve got a secret (running shoe)

Yesterday’s run (treadmill): 25 minutes

I’m having another busy week that has caused me to miss two blog posts and today’s workout. I’m hoping to get back on track tomorrow. In the meantime, I’ve been enjoying the experience of testing a new pair of running shoes for a company that I cannot name. In the past, I’ve been provided a good number of running shoes for review, but these models were already available in stores. I did receive my Kinvara 3’s a month before retail launch, but had no influence on their design.

The shoes I’m evaluating are a work in progress and they will surely change before hitting the stores. I’ve done two runs in them (both indoors) so I’m curious to see how they feel on the road. They happen to be the type of shoes I’d consider as a primary trainer, and that makes the testing especially interesting. I filled out my first feedback report yesterday and liked being able to share my opinions with those who can shape the final product. I’ll provide all the details once the testing is done (and I get an okay from the company to do that).

This video ad from Nike has been going around for a while, although I only saw it this week. I’m not a fan of Nike running shoes (my test shoes are not Nikes) but I really liked this commercial. It made me laugh when I watched it.

Kinvara 3, Spira Stinger faceoff

Kinvara 3’s – a worthy successor to the original
Spira Stinger XLT’s – light, fast and comfortable

With less than six days until the LI Half Marathon, I’m still undecided about which shoes to use for the race. Six months ago I wouldn’t have hesitated to go with my Hattori’s, but I haven’t run with them much over the last two months. I’m not sure how those flat, non-cushioned shoes would feel after 13.1 hard miles, especially with my recent issues with mid-foot pain.

It has really come down to two shoes to wear – the Saucony Kinvara 3 and the Spira Stinger XLT. The Kinvara 3 is a minimal running shoe that I’d anticipated for a year, only to be initially disappointed when I finally ran in them. My issues, it turned out, were not with the shoes, but with the foot inside. An acute pain along my left mid-foot was actually a slight injury that has since healed.

The other candidate shoe, from Spira, has been a delightful surprise. I agreed to evaluate this model on Runner’s Tech Review, thinking they were the type of gimmicky running shoes I often lampoon. It turns out that the Spiras are one of the most comfortable and runnable lightweight shoes I’ve ever encountered. As far as their promise of slicing 15 seconds per mile off my pace, I’m not so sure I’m seeing that benefit. But the Stingers have carried me well over many 8+ mile runs.

I wore both pairs on my runs this past weekend and I’m definitely leaning toward the Kinvaras. While the Spiras have their energetic “Waveform” technology, the Kinvara 3’s feel like my original Kinvaras, the highest compliment I can give to a running shoe. Saturday’s 12 miler was grueling, but my feet felt great. The light weight and low platform of the Kinvara 3’s have almost convinced me to go that way. Almost.

Stingers, Kinvaras or Hattori’s? A hard choice to make

Hard to argue with success

I’m less than two weeks away from running my fourth consecutive Marcie Mazzola race.  The first time I ran it was in 2009 when the distance was 4 miles. The course was shortened the next year to 5K to increase the number of participants. What didn’t change was the big hill on Woodhull Road that makes up a good part of the first mile. After three races along that course, I’m actually looking forward to the hill challenge this year.

Once runners get past the big hill, the course reverts to a net negative elevation, providing some great opportunities to let loose on the downhills. I’m on the fence about which running shoes I’ll use for this race, but I’m thinking it may be between my latest two pairs: the Spira Stinger XLT’s and the Saucony Kinvara 3’s.

I’ve done my last two long runs in the Spiras and they have performed exceedingly well. I was prepared to dismiss them as a gimmick when offered the opportunity to test them on Runner’s Tech Review and I’m glad I stayed open minded. Make no mistake about this shoe – it’s lightweight, comfortable, supportive and responsive.

The Kinvara 3’s are also very nice. I loved my original Kinvaras but found the Kinvara 2’s less appealing each time I tried them on. To be fair, I never ran in them, so I don’t really know how they’d have performed. I do know that the Kinvara 3’s feel more like the original and, with their 4mm ramp angle, suit my preference for a lower platform. I have had noticeable irritation in one foot when running in these shoes, but I suspect it’s as much a foot issue as it is a shoe problem.

It’s hard to determine which of these shoes would serve me better for a fast 5K. Perhaps I’ll simply opt for door #3 and run with the venerable Hattori’s. These shoes, despite over 300 miles on their thin soles, still deliver one of the best running experiences I’ve ever encountered.

First impression: Spira Stinger XLT’s

Float like a bee?

Today’s run (treadmill): 25 minutes

Yesterday I posted about two pairs of mystery shoes and last night I got to try on the first pair. They are lightweight running shoes from a company called Spira, based in El Paso, TX. Spira shoes contain something called “Wavespring Technology” where specially designed springs are embedded within the mid-sole to enable better energy return to runners and walkers.

The shoes I received are Spira’s performance model, called Stinger XLT. I think they are called Stingers because (with their bright yellow and black highlights) the shoes resemble a bumble bee. I don’t judge shoes on the way they look, but people who like their running shoes to be noticeable will not be disappointed.

I took the XLT’s out of the box and had two reactions. First was, “That looks like a lot of shoe, I’ll bet they’re heavy.” After picking them up I thought, “How can a shoe containing metal springs be this light?” I put one on my foot and was pleased with the comfortable foot bed. It’s a well cushioned shoe and while I usually prefer the other end of the spectrum (Saucony Hattori’s), I appreciated the comfortable fit.

I’d asked for size 11’s, 1/2 size up from what I usually wear, because lately I’ve had issues with tight toe-boxes. The XLT’s fit me well and the toe-box was fine. A quick run around the house reinforced that, lots of room, but no slippage. I checked the morning’s weather and it said rain, so I decided to try my first run on the treadmill.

After two relatively long runs over the weekend, my feet were a little sore and the XLT’s provided a nice cushioned base. The Wavesprings do not create a “moon-bounce” effect. In fact, it would not be obvious to someone that this shoe contained any special technology. The XLT’s do provide a decent response though, not unlike my Brooks GTS 10’s in their early days.

The shoes performed very well on the treadmill. They moved naturally with my foot, felt stable and returned good energy. I couldn’t test the predicted 15 sec/mile improvement communicated to me by Andrew B. Krafsur, Spira’s founder, but I found it surprisingly easy to maintain a sub 9:00/mile pace once I got going.

I’m planning to try the shoes on the road tomorrow morning. If they perform well I’ll use them for at least one of my long runs this weekend. My most popular post is titled “Tubes, zig-zags, bounces, shocks and resistors” which is about gimmicky running shoes that fall short of expectations. So far (and surprisingly), the Stinger XLT’s appear to be the real deal.
