The Speedgoat 6 GTX is now even more comfortable with GORE-TEX's Invisible Fit waterproof membrane for a lighter, more flexible construction to help avoid pressure points. Grounded in a Vibram?? Megagrip with Traction Lug outsole for increased bite on loose soil, this trail icon employs a foot-cradling heel bolster, lightweight, responsive midsole compound, and a protective toe rand for charging through the rough stuff. Bring it, weather.
