Patented material and design create the ultimate cross country boot. The mesh outer layer provides 360 degree protection with a lightweight rip stop surface that wont retain water and is breathable to aid in cooling of the legs. The non-slip lining prevents slipping and rubbing. Inside the boot is a revolutionary strike guard made from high quality TPU that is flexible and conforms to the shape of the leg, but will harden to a rigid protective wall upon impact. Sold in Front and Rear Pairs.
