MP Tan™ is a high rebound urethane foam absorbs shock, the same material as MP Blue & MP Black. That's it. No other orthosis material does it as well. According to the guys in the lab, when the weight-bearing foot strikes the floor, MP urethane matrix efficiently redistributes the wearer's kinetic energy, preventing it from returning up the leg, wreaking havoc on bones and tissues.
