DOR Podcast #97: All of Your Saucony Endorphin Speed 3 Questions Answered

The new version is, in our opinion, better than ever, boasting a wider platform, more stability, and the same bouncy PWRRUN PB midsole foam. They also tackle a bunch of listener questions about the Speed 3 including: how soft is it? How's the heel stability? How does it compare with the new Saucony Tempus?

Science Blog: What does lateral heel wear mean?
By Chief Editor Matt Klein

Excessive lateral forefoot wear is a fairly common thing that I see. Usually this means that someone is supinating or inverting excessively during toe-off.  This could come from a fibularis longus weakness and the body is avoiding putting pressure on the first metatarsal.  It could come from excessive tightness of the calves or the posterior tibalis.  It could also be coming from a forefoot striker landing very hard on the lateral aspect of the shoe, which is fairly normal for their gait.  This is similar to landing on the posterior lateral side of the heel.  Most people will land on the outside first to prepare themselves for pronation, which again is a normal method of shock absorption.

While this is only briefly mentioned in the research, I often look for asymmetrical wear patterns.  Generally more wear on one shoe versus the other makes me suspect either weakness, abnormal biomechanics or possible leg length discrepancies.  Most individuals will land harder on sides that have poor eccentric strength and will instead use joint loading instead of muscle loading for shock attenuation.  While asymmetry to a certain degree in the human body is normal, excessive is not and can (but not always) be predictive of injury risk.  However, this can also occur if you tend to run or turn asymmetrically in some fashion.  An example being if you run on a track exclusively in one direction.  You are constantly going one direction, which places asymmetrical loads on each side of the body. That is why I am a huge proponent of doing workouts both ways on the track for athletes to reduce risk for asymmetrically induced overuse injuries (a common issue I see is sacroiliac joint issues, but this is anecdotal).   Another great example of this is running on the same side of the road all the time.  The cant of the road acts like a wedge and will cause asymmetric loading if you don't find a level surface or make sure you spend equal time on the other side.
