Women's SAUCONY® PEREGRINE 12:Named for the fastest bird on earth! Soaring in at 8.2 ounces, your updated Women's Saucony Peregrine 12 trail running shoes are over an ounce lighter than their predecessor and amped up with more speed than ever before. Featuring a redesigned lug pattern that won't pick up unwanted debris, you also get PWRTRAC rubber for maximum traction and grip. Plus, the more flexible rock plate actually sheds moisture while giving you underfoot protection. To further impress, the Peregrine 12 is designed with a fresh upper made of recycled materials that won't disappoint.
