The Super Light™ insole offers maximum performance cushioning. The PORON® cellular urethane provides a superior cushion for the crucial heel and forefoot areas. The 3 part support system includes an anatomically shaped, extra deep heel cup, external heel stabilizer, and arch support; all working together to properly support the foot. 10% - 30% lighter than other performance supportive cushions, the Super Light™ will give you the support you need and performance your wanting. The Biostatic™ top cover helps fight against unwanted odors. By controlling the amount the foot slides across the insole's surface, the anti-friction top cover helps prevent blisters and keeps feet cooler and drier.
