Powerstep Pinnacle Maxx takes it to a new level of pain relief and prevention for overpronators. Our exclusive Heel Secure Comfort System now offers a deeper heel cup with a very slightly angled exterior heel platform and a firmer shell for greater control, and to help further correct foot alignment. It still has all the features you love about the Pinnacle including double-layer cushioning featuring Hypurcel, prescription quality support structure, and an anti-bacterial top cover.
