Men's Hoka Speedgoat 5 Running Shoes The Speedgoat has less weight and more traction. A new shoe from outsole to laces, this trail beast is updated with Vibram Megagrip with Traction Lug for enhanced grip on loose soil. Retaining the same stack height and rocker profile, the Speedgoat 5 employs a lighter midsole compound and heartier, double layer jacquard mesh to inspire confidence on any terrain.
