Inspired by Karl Melzter, 100-mile trail race record holder, these men's Speedgoat 2 Trail Running Shoes from Hoka One One attack all types of terrain. Redesigned for an even better fit, more stability and more durability this is one fast, hard-wearing trail shoe. A new last and wider midsole creates a stable platform, with a wider toe box and reinforced toe area for supreme protection from sharp objects. Deeper, aggressive Vibram lugs on the outsole hold out on challenging terrain, with a forgiving upper for mile after mile comfort.. Material: Textile & Synthetic Upper/Synthetic Sole
