ThePro Sport insole delivers maximum performance cushioning.

The PORON cellular urethane provides a superior cushion for the crucial heel and forefoot areas.

The extra deep heel cup helps cushion the foot naturally, utilizing the natural cushioning tissues in the heel of the foot.

Air flow channels are molded into the shape of the arch to help move warm air out while drawing cooler air into the footwear.

The Biostatic top cover helps keep the insole odor free. Also, the anti-friction in the top cover helps prevent blisters and keeps feet cooler and drier.
