The Hoka One One Men's Speedgoat Trail Running Shoes were inspired by Karl Meltzer and the rugged conditions of the Speedgoat 50K. The Speedgoat was designed to take on technical trails. Built on an injected EVA midsole, and with 4mm Vibram rubber lugs, the Speedgoat is built to tackle technical terrain with ease. The upper provides support all the way through the forefoot, and the ground-rubber toecap gives increased toe protection. When you need a tough shoe to get you through tough trail conditions, look to the Speedgoat.
