Inspired by Karl Meltzer, aka "The Speedgoat", who holds the record for the most 100-mile trail race wins and epitomizes the "go everywhere, run everything" attitude, this shoe is designed to attack all kinds of technical trail. In this waterproof version we've added a SKYSHELL waterproof bootie and gusseted tongue. The wider midsole and toe box of Speedgoat 2 were well received, as were the more aggressive Vibram Megagrip lugs, which hold up to all kinds of rugged terrain. With the Speedgoat 3 WP, we've added further heel support and mid-foot lockdown in the upper as well as 'seatbelt' support on each side. It's a combo that creates a protective cradle. Topped by a patterned ripstop nylon upper, we think we're really in lock step with the Speedgoat's "go everywhere, run everything" philosophy.
