The North Face Hedgehog Fastpack GTX Hiking Shoe - Women's. Size 8.5. Still In Great Shape! Hedgehogs are renowned for their hiking prowess and natural waterproof qualities, which is why The North Face named its dry, supportive, and comfortable women's hiking shoe the Hedgehog Fastpack GTX. Unlike its namesake, the Hedgehog's upper is made from PU-coated leather and mesh, with a super-sticky Vibram outsole that's designed to crush rock, dirt, and slick wet ground with equal aplomb. A waterproof and breathable Gore-Tex membrane keeps your foot dry when you're splashing through puddles or hiking in the rain, and the Cradle Guide EVA midsole, TPU heel cradle, and TPU shank provide lightweight cushioning, ankle-saving support, and protection from rock strikes and rugged ground.
