Running Shoe Rotation Frustration

The Shoe-pocratic Oath: "First do no harm"

Unless you're Abebe Bikila, the barefoot marathoner who won the Olympic marathon in 1960, shoes are pretty essential gear. Though some runners are indifferent to what shoe they wear and view them as tools, others (like me) look at shoes as something that can greatly enhance or diminish their running experience. I love running shoes but they don't always love me, and I'm dealing with that right now.

The Problem

In my last post, I mentioned some issues I'm having with my lower back. Recently, I've been feeling occasional pain and numbness along my right leg, hip and glute when I run. I suspect it may be a reoccurrence of a 2015 disc problem. Back then, my undisciplined training caused the rupture of my L4 and L5 discs, as well as a torn annular ligament. As a result, my orthopedist strongly recommended that I stop running for almost five weeks. 

High Octane alternative motion contraption

During that time, I was at Consumer Reports and had the opportunity to participate in a panel to test "alternative motion machines." These devices functioned like advanced elliptical machines and provided an excellent daily workout. This "zero impact" training helped my disc problem and I recovered well enough to resume my daily runs.

Fast forward seven years and I'm dealing with similar symptoms. My gait is awkward at the start of my runs but it settles down after a few minutes. Due to that, my first miles have been 30-40 seconds slower than my second. I've been running well and feel ready to add more distance. I'm holding off on that because the symptoms are reappearing once I reach the three mile mark.

The Cause

I believe that some of my running shoes are either causing or exacerbating my leg problem. I under pronate and originally ran in stability shoes like Brooks Adrenalines and ASICS GT 2140s. When I started Runner's Tech Review, companies would send me models of their newest running shoes to test. From that, I developed a preference for lightweight neutral trainers like the Saucony Kinvara and that became my default. I still prefer neutral running shoes, but they may not be a good choice for me.

My under pronation worsened after my disc and ligament problem. I started to notice how quickly I was wearing out the lateral side heel of every pair of shoes I had. I'd get 800 miles on a pair of Adrenalines but less than half of that with non-stability models. When I looked at the three oldest shoes in my rotation, I was surprised to see how much wear they showed. The difference in heel height from side to side was greater than 3mm. This is a recipe for running injury.

Worn to Run

I concluded that 60% of my running shoes were no longer runnable. That left me with two pair, the Saucony Kinvara 11s and the Reebok Floatride Run Fast 3s. Neither of these shoes have much mileage on them yet, but the Kinvaras are already starting to show a similar wear pattern. The Reeboks are still pristine and I want to preserve those peppy and propulsive shoes as long as possible.

Searching for Shoe Love

After looking up every single running shoe on the internet, reading every review and watching every video, I narrowed it down to a few models. Included in this group was the Hoka Rocket X, which is described on the Hoka site as, "...an incredibly lightweight, insanely responsive racer geared for elite athletes."  Check, check and check!  I don't want to brag, but I did take second place in my age group in a 2009 5K.

Despite deep devotion to Hokas by my fellow Runsketeers, I've always resisted the brand. They just seemed too high and bulky for my taste. When I stumbled upon a site called Hoka Outlet and saw the Rocket X for sale for $49.95 in my size (these shoes typically sell for $199) I thought, what do I have to lose? Answer: $49.95 plus tax. Yes, it was a scam.  I did manage to get my money back from PayPal, but I'm embarrassed by my naivety. 

Beware of Hokey Hokas

An Unlikely Solution

After the Hoka con, it was back to square one. I would continue my search for new shoes, but I wanted at least one additional pair right away. I considered my NB 680s that I use on the treadmill but I don't like to use my indoor shoes outside. I was about to grab my keys and head to the nearby DSW store to buy a cheap pair of stability trainers when something green caught my eye. Tucked under some winter clothes in my running gear closet was an 11 year old pair of Karhu Fast 2s that I'd tested and then quickly discarded.

Lapland Lappers

Karhu sent me these light-ish but high riding performance shoes to test during a period when I was wearing ultra minimal zero drop shoes like the Brooks Pure Drifts and Saucony Hattoris (below). The Fast 2's at 9.6 ounces were anything but minimal.

Hattori - 4.4 oz

Pure Drift - 5.6 oz

The Karhus were probably ahead of their time with their high stack height and "fulcrum" technology that facilitated a rolling gait. I found them awkward in 2011, but when I put them on now they feel cushioned and well balanced. Since I used them only to test, the shoes are still in like-new condition. I took them out for a run and appreciated the forward leaning motion and the responsive midsole. My pace almost matched the Reeboks, which are considered a bona fide racing shoe.

With my Finnish flyers added to the mix, I'm only short one pair to round out my rotation. The Kinvara is a light trainer that works well for tempo runs. The Reeboks are speedy and fun, perfect for intervals and when I want to run my fastest. The Karhus sit somewhere between these two. I'm going to focus my search on cushioned but light stability shoes that provide a responsive ride. I may end up paying more than I ever have for a running shoe to get what I want, but it will be worth it. Who knows, maybe I'll stumble upon an outlet that's selling Saucony Guide 15s or ASICS DS Trainer 26s for $60.

Either way, I'll let you know. 🏃

Supinating is how I roll

Today's run (street): 4.3 miles
Yesterday's run (street): 5.1 miles

Fall is almost here and I'm loving the cooler temperatures. Unfortunately, the humidity still thinks it's summertime. That's true, but running conditions have improved over August's dog days. Stepping out to mid-60's temperatures provided a welcomed boost this morning. I had two good runs this weekend, even though my positive performance from Friday wasn't duplicated on either day.

Yesterday I broke out of the boundaries of my neighborhood, venturing into the nearby business park and the neighborhood that connects to it. I'd targeted 5 miles and ran easy. That turned out to be a good idea because the humidity was an oppressive 88%. This morning felt cooler and a moderate breeze from the north provided a nice offset to still-present humidity. I'd considered a trail run but didn't want to deal with mountain bikers at Stillwell. I ended up staying local.

The best thing about today's run was that my energy level was running a few notches above usual. Feeling stronger prompted me to step up my pace and open my stride. It was during my run on Saturday that I noticed how my form has changed since dealing with my herniated disc. I still have slight discomfort in my left thigh, especially when I push my speed.

After yesterday's run, I looked up strides and landing styles and realized for the first time that I am actually not a pronator. That label was given to me seven years ago by the salesperson at Super Runner's in Huntington after she watched me walk across the store. That resulted in my purchase of a pair of Brooks Adrenaline 9's that I loved dearly and wore for 1,000 miles.

Although pronators are supposed to wear stability trainers, I've always felt comfortable running in neutral shoes, especially the minimal variety, That explains my love for the Kinvaras and my appreciation of the Saucony Virratas that I recently replaced with the Kinvara 5s. The article I read showed wear patterns and connected them to different types of strides: pronator, over-pronator, neutral and supinator.

According to the illustrations, I'm a supinator, someone whose foot rolls outward on landing. I looked at my Virratas, the shoes with the most outdoor mileage, and the wear pattern clearly shows that I do this. So now I'm confused. Stability shoes are built with a medial post or some type of multi-density material in the mid-sole to neutralize inward rolling. I get that. What I don't get is when I look up "best shoes for supination" most results point to stability shoes. But since it's the opposite problem, wouldn't stability shoes amplify supination?

While the running world works to figure that out, I'll stick with my minimal neutral models. The only downside to that is my preferred shoes use a fairly soft material on the out-sole that is apt to wear out from all my supinatin'. Still, I'd rather run in shoes that feel right, rather than ones that are made for people who supinate. So far, that seems to be the right approach.

The pendulum of minimalism

Today's run (street): 3.3 miles

I was reading an article that said the demand for minimal-style running shoes, once a growth segment, is beginning to decline. The book, Born to Run, made many people curious about barefoot-style running, and it forced us to reconsider the merits of the shoes we've always bought.

A few years ago, I saw a video of myself on the treadmill at Jackrabbit Sports. That clearly confirmed that I'm an over-pronater. The salesperson recommended that I buy a beefy, medially-posted "stability" shoe to correct that tendency. After all, they said, my stride made me susceptible to knee and IT band injuries. I wished at the time that I could wear a lighter shoe, but I feared the consequences.

Hattori

I thought about all this on my run this morning. The idea that shoes with lots of cushioning would prevent certain types of injuries has been increasingly debated and challenged by many. That includes me. I wore out a a pair of Saucony Hattoris after 400 miles and I now run primarily in the Brooks Pure Drifts, Brooks' most minimal shoe. The Hattori and Drift are both simple designs. Each shoe weighs less than 6 ounces and neither has any stability features. After more than 700 miles running in that type of shoe, I haven't encountered a single problem.

Pure Drift

The dash toward barefoot running probably got too many people into minimal shoes too soon. Many are now going back to more cushy footwear. But the game has changed, and now even stability shoes have lighter construction. I know that many people feel that the shoe makes the runner. After 3+ years of (mostly) injury-free running, in barely-there neutral trainers, I respectfully disagree.

Puzzling find beneath my Hattori's

Hey, that's nowhere near my mid-foot!

I did both of my weekend runs on the treadmill and used my second pair of Hattori's that have yet to see pavement. Out of curiosity, I looked at the bottoms to see if the tread picked up a wear pattern from the belt and noticed some evidence of impact on the front medial side. That looked like I may still be pronating, even with a mid-foot strike. I also thought that it may just be belt dust that attached to the out-sole.

When I looked at my primary pair of Hattori's I was quite surprised to see that both heel pads showed clear evidence of wear towards the outside edge of the shoes. These are outdoor shoes and there's no other explanation except that I'm still pushing off the heel at some point in my strike.

This is puzzling because I know I'm landing on my mid-foot when I run in the Hattori's and the white EVA shows an imprint that supports that fact. Clearly there are two points of contact when I land and I'm guessing that I glance off the heel and then strike ahead of the arch. No too bad but not what I want. Perhaps I'll make a trip to a local running store in the next couple of weeks and ask to have my gait videoed. Even if my theory is confirmed I'm not sure if there's much I can do unless I want to go back to a lightweight stability shoe.

Kinvaras as a daily trainer?

These cool Kinvaras are becoming my everyday shoe

The transition to fall weather makes me happy. Although it will take some time to adjust my running gear so that I don't go out under-dressed like yesterday, I still welcome the change. This morning the temperature where I live is 51 degrees, perfect for a run but quite chilly when standing on the train platform. I always wish for this weather when enduring the heat of summer or the frigid cold in January. I'll enjoy it as long as I can.

I wore my Saucony Kinvaras during yesterday's run and I've started to really appreciate them. Lightweight but not insubstantial, they are minimally constructed but still reasonably supportive. The Kinvara is a neutral shoe and I thought I'd have trouble with it because I pronate when I run. I've had some 8+ mile runs with them without experiencing any problems with my knees or legs and that brings me to question the idea of stability shoe engineering. I suspect that because the drop off between heel and forefoot of the Kinvara is only 4mm, compared to 12mm, (common for standard trainers) the shoe facilitates a more natural mid-foot landing. This would logically neutralize the effects of pronation. I continue to rotate through my other pairs and still consider my Brooks GTS 10's my everyday shoe, but the Kinvaras are forcing me to rethink that these days. If I do move primarily to the Kinvaras I'll need to consider their durability and the thermal properties of the barely-there uppers compared with the Brooks' more substantial build. After all, it's getting colder out there these days.

Does form follow function?

Last night, on my way down to Penn Station, I observed a runner making his way through the crowded mid-town streets. I wondered, with all the great places to run in NYC, why he picked Time Square at rush hour. What I noticed about this runner was how inefficient he looked as he ran. His stride reminded me of Elaine's dancing on Seinfeld with both feet splaying left and right and his elbows were swinging like a race walker. It made me wonder whether this was an extreme example of pronation or supination or just poor technique.

I began thinking about my own form and as I came into Penn I began watching my feet to see if they did anything strange when I walked. They looked fairly straight and I questioned whether that was due to my conscious observation. Walking with my head down was not smart because I almost ran into some people so I stopped the experiment without reaching a conclusion. I tried to look again during this morning's 4:00 AM run but quickly (and smartly) chose keep my eyes focused on the road.

There are a number of running stores in NYC that have treadmills and video cameras that allow sales people to capture a person's stride so they can recommend a specific shoe or shoe type. A ten second walk across the floor was all the analysis done to put me in my Brooks so I really don't know if I'm an efficient runner. I'm thinking about my next pair and whether I want to price shop for what I think I want or if it's worth paying more to find out what I really need.
