Known as the fastest animal on earth, the Peregrine 13 soars above all. Packed with more cushioning, and lighter-than-ever, this bird is back in a featherweight combination to go farther, faster. This shoe comes with padded protection and a lightweight PWRRUN foam for comfort that goes the distance. The PWRTRAC lug system offers precision grip to dig in with confidence, along with a trsuted rock guard for protection on uneven trail surfaces.
