Balance & Vertical Impact: Role of Shoe Sole Materials

If you think cushion under the foot is good and/or if you wonder if cushion is related to running injuries, check out the article posted by my friend Luis:

It's actually quite logical if you think about it. Traditional running shoes create an unstable landing and base that causes increased impact through reduced flexion at the hip and knee so as to briefly achieve improved stability by compressing the interface materials of the shoe sole, and the force to create the compression increased the impact.
