There is nothing comfortable or attractive about sweaty, stinky feet, and luckily there is an easy remedy. Outlast^® insoles keep your feet comfortable by absorbing excess body heat when you create too much, storing this heat, and then releasing the heat back to you when you need it most. By incorporating Outlast^® technology into your footwear, you can reduce moisture build up by over 40%. This decrease in sweat will help reduce heat loss and hot spots, which can lead to blistering. The insoles are made with a 100% Poliyou® base. This open cell Polyurethane foam provides the perfect blend of cushioning, support, and moisture management. Throw on a pair of Outlast^® socks for even more comfort and moisture management.
