A nylon arch support comfortably stretches the plantar fascia, while the engineered bridge ensures that arches don’t collapse, keeping the feet in a neutral position. Gel heel cushions absorb impact for all day comfort. The Spenco Rx Men’s Full-Length Plantar Fascia Insoles fit men’s shoe sizes 7-13. Shoe inserts are trim-to-fit and odor-resistant.
