The Merrell Women's All Out Peak GTX Trail Running Shoe has cushion for miles and more protection so you can go all out in any condition. Merrell Gore Tex Connect Fit gives you guaranteed waterproof, breathable protection in a natural fitting shoe, and the HyperWrap 360 Degree Fit System locks your foot in place for enhanced stability and performance. Breathable mesh lining readies this shoe for warm weather runs in the mountains. Underfoot, Merrell equipped the All Out Peak with a UniFly midsole for maximum cushioning, terrain absorption, and agility. Merrell also added a removable footbed for more cush and convenient cleaning. The TrailProtect pad offers underfoot protection, and Vibram's reliable rubber keeps the sole strong for seasons.
