Made from mesh knit top material for maximum air flow. Gel layer inside sock is for active kids who need additional heel pain protection. US Kid's Sizes 1-6 </b></p> <p> We are very excited to introduce our new line of RX Socks. Any child who suffers from Severs Disease, Plantar Fasciitis or any other undiagnosed heel pain issues will benefit significantly from our new line of Gel Sport RX Socks. By adding a gel layer within the heel of the sock, your child now has added layer of comfort that NEVER slides or moves in their shoe. We created the line of Sport Gel Socks because active kids have issues with their heel pads and heel cups staying in place while they play. Now they can easily keep the gel protection layer in place while they play sports or exercise. Here at KidSole we never stop listening to our customers. We are always finding new ways to help your kid's feel better in their shoes. We believe in all our products and stand by our unconditional 30 Day Money Back Guarantee.
