I'm selling this because the size didn't fit. I bought it because it was a limited edition, but I only wore it once and then put it away... The following is a quote from the manufacturer: Puma soccer cleats. The Future series, with the concept of "next-generation soccer shoes." Equipped with the NETFIT system, which allows for fit customization through the way the laces are threaded, and an evoKNIT sock structure that wraps the foot. Suitable for hard and artificial turf grounds. ◆ Limited-edition item available at select stores Upper: Synthetic resin (polyurethane), synthetic fiber Outsole: Synthetic resin sole (polyurethane) Suitable ground: Soil ground, artificial turf ground Foot width: Regular fit Color: Red Blast
