MP BLACK
MatPLUS Brand
MP BLACK™ is a high rebound urethane foam absorbs shock, same as MP BLUE & TAN. 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.
