Surely the folks at ASICS must be aware of 2016 Converse Pas Cher the paper by Ryan et al., 2010. They showed that neutral runners did better in stability shoes, overpronators did better in neutral shoes, and all severe overpronators in motion control shoes got hurt. In other words, either the shoes don¡¯t do what they are supposed to, or static measures of the foot are not a good basis for assigning shoes. And the study was supported by Nike.

As I have written previously here on Runblogger, forefoot striking has been shown to reduce vertical impact peak (many studies, Squadrone and Gallozi, 2009 and Lieberman et al., 2010 are recent examples) and vertical impact loading rate (Oakley and Pratt, 1988; Williams et al., 2000) relative to heel striking. Data showing no difference between forefoot and rearfoot impact loading rate is out there (e.g., Laughton et al., 2003), but data are limited that involve people well acclimated to multiple landing types. Data on loading rates are sometimes difficult to interpret if runners are not acclimated to a barefoot running style ¨C for example, De Converse All Star Chaussures Wit et al., 2000 showed dramatically increased vertical loading rate in barefoot runners compared to shod runners, but their barefoot runners were heel striking. One would fully expect a barefoot heel strike to exhibit a higher loading rate since little cushion other than the heel fat pad is present to slow down force application. Lieberman et al., 2010 showed that habitually barefoot runners overwhelmingly land on the forefoot, which suggests caution when interpreting studies of barefoot heel strikers (who were probably unaccustomed to running barefoot). See this recent (2011) paper by Jenkins and Cauthon in the Journal of the American Podiatric Medical Association for more on this issue.

Moving along, Bartold next says this:

Last time I checked, a change in footstrike is itself a kinematic change. I was unable to find this reference anywhere, so hard to evaluate it, but kinematic changes have been shown many times between rearfoot and forefoot strikers. For example, consider this statement from a conference abstract by McClay and Williams, 1998 (published later in the Journal of Applied Biomechanics as Williams et al., 2000):

¡°I think unquestionably Zola Budd got it right when she was running barefoot. I think the signs from all the laboratories around the world would support that the human foot is probably the perfect model, but of course it¡¯s impractical for most people wanting to go out running barefoot, there are too many obstacles, and of course you know, you might get injured by a sharp object, and the surfaces we run on transmit to Converse Limited Edition Pas Cher o much shock. But in a perfect environment on a perfect surface, then an unshod foot is probably the best way to go.¡±

I¡¯ve been following with interest a spirited debate that is taking place over on my friend Bill Katovsky¡¯s Zero Drop blog. Like me, Bill is an advocate for greater variety in shoe choice, and his approach on his blog is to poke fun at the status quo in addition to providing the occasional shoe review. He also has published a number of interesting guest posts ¨C his blog i Noir Converse Pas Cher s well worth a look if you haven¡¯t seen it already.
