Interesting to compare how the different types of foot strike are distributed among runners wearing different shoes. If I counted correctly, there are 8 runners wearing either the Kinvara or Mirage, and 4 of them are heel strikers, 1 midfoot striker and 3 forefoot strikers. (On the other hand, two Type A5 users are heel strikers.) Also many Lunaracer (and other lightweight Nike shoe, Zoom Streak perhaps) wearers seem to be forefoot strikers. With Adidas Adizero shoes, some runners do forefoot and midfoot strike, but many also have a pronounced heelstrike.

The heaviest and most overstriding heel strikes can be seen with Mizuno and Asics wearers. I don't notice anyone forefoot strike with Asics shoes. But isn't that what Asics aims at since they believe in heel striking. :)

Very interesting. If you look carefully, you can tell by the way the runner is pushing off the ground if he will be a hill striker or not. Forefoot striker do not skip the push phase (see photo) while hill strikers do. I wrote about it in my blog (http://www.leplaisirdecourir.blogspot...). Sorry it is in French ;)

Thanks for the quick analysis - I might have to go back and tally up the numbers for each now and do another post!

Do some of the runners really heel-strike in the sub 1:30 group? Doesn't the big heel just have contact with the ground? I can imagine if you x-rayed their foot strike, that you would see the heel being just off the ground, contacting it only thanks to the heel. The latter not because they can but because of the additional material. I am not sure I am getting my point across right ...

Yep, lots of heel striking even among faster runners, but also lots of variation among the heel strikers.

Interesting correlation, never thought to look at that. Makes sense that if you do it get good hip extension on the back side you have to reach out on the front and overstride to compensate and maintain adequate stride length.
