Several interesting studies have come out over Nike Lunar Cheap UK the past few weeks that have in one way or another focused on the running foot strike. The first that I¡¯m going to cover is by Jason Bonacci and colleagues and addresses how running mechanics differ between barefoot running and running in a ¡°minimalist¡± shoe (Nike Free 3.0), racing flat (Nike Lunaracer 2), and ¡°regular¡± running shoes (a runner¡¯s typical training shoe, variable by individual). The study is titled ¡°Running in a minimalist and lightweight shoe is not the same as running barefoot: a biomechanical study¡± and was released in Online First form on the British Journal of Sports Medicine website.

The real standout here in terms of biomechanical differences was barefoot running. Here are some of the key differences that were found for barefoot relative to the shoes:1. shorter stride length than all shod conditions 2. higher cadence than all shod conditions (avg. 187.7 steps/min) 3. less dorsiflexion of the ankle at initial contact (i.e., flatter foot placement at contact) 4. greater ankle plantarflexion at toe-off 5. reduced knee extension and abduction moments Posted Image 6. less knee flexion during midstance (straighter leg) 7. smaller joint moments and less work done at the knee (24% less negative work when barefoot compared to the standard shoe) 8. greater joint moments and more work done at the ankle

The authors summarize by saying: ¡°Knee and ankle mechanics when running barefoot were different to all shod conditions, including the minimalist shoe, indicating that the minimalist shoe cannot entirely replicate the mechanics of running barefoot.¡±

The researchers filmed the runners with a 22-camera 3D Vicon system on an indoor track, and measured force using 8 force plates (this was a pretty high-caliber setup). The combination of cameras and plates allowed them to capture biomechanical data from a 20m long section of the track.

Given the above features, I view the Nike Free 3.0 as a great choice as a transitional shoe if you¡¯re thinking about working your way down to running barefoot or in an extremely minimalist shoe like the Vibram Fivefingers. Some disagree with this approach, saying that going barefoot from the start is the best approach so that immediate sensory feedback from your feet can prevent you from doing too much, too soon, but the transitional approach worked well for me, and I have managed to avoid any serious injuries so far while running in Vibrams over the past 8-10 months (I should point out that although I¡¯ve tried barefoot running, I¡¯m not a barefoot runner). The important thing to remember with any new shoe, and with minimalist shoes in particular, is to not overdo it ¨C give your fee Nike Air Max 90 Mens UK Sale t and legs time to adjust to these shoes, and resist the urge to do too much, too soon.

The original idea behind the Nike Free was to create a shoe that simulates running barefoot on grass, and though I¡¯m not sure I¡¯d say that they replicate that experience perfectly, they do have a very different feel than most shoes on the market (super flexible, silent underfoot). One might even argue that the Free was a minimalist shoe before the phrase ¡°minimalist shoe¡± even existed, and the original Free is a sho Nike Air Max 90 Womens UK Outlet e that will be remembered as a milestone in footwear innovation.
