The long, stiff F-70 will enhance your performance on the trail. The shoe's seamless upper is made of three layers of extra-thick XD-Knit nylon yarn, so it can adapt to the shape of your shoe and the contours of your foot. Additional protective layers at the toe and heel prevent injury and soiling. The Dial lacing system uses a single ATOP actuator and Velcro strap for a secure, precise fit at every point on the foot. The F-70 is manufactured with an M-250 outsole with new injected fiberglass and widely spaced TPU soles with replaceable spikes. The outsole thus offers stiff pedaling performance, portability, uncompromising durability and arch support. At the same time, it's comfortable and won't deform, even over time. The EVA footbed is contoured, breathable and removable.Weight 318 g
