Polysorb Cross Trainer Insole Women's 5-6.5/Men's 4-5.5

The Spenco Medical Polysorb Cross Trainer Insole is engineered to deliver an elite combination of shock absorption and energy return, making it a smart upgrade for runners, athletes, and anyone logging serious time on their feet. Spencore material cushions impact throughout the foot while polyurethane foam supports the arch and heel, a Spencore heel plug adds extra shock absorption, and an SBR forefoot cushion maximizes energy return for high-impact movement. A 4-way stretch top layer keeps blisters at bay and fights odor with Silpure antimicrobial technology, so your shoes stay fresh.
