Inspired by Karl Meltzer, who holds the record for most 100-mile trail race wins, the fastest completion of the (2,190 mile) Appalachian Trail, and epitomizes the go everywhere, run everything attitude, this shoe is designed to attack all breeds of technical trail. And with this bold, fully redesigned iteration, we`ve improved fit, stability, and durability. Built on a new last, the wider midsole creates a more stable platform for the foot and offers a wider toe box with reinforced areas where your feet need them. The outsole features deeper, more aggressive Vibram lugs which hold up to all kinds of rugged terrain, while the more forgiving upper offers improved comfort up top. The SPEEDGOAT 2 means business. This is one fast, tough trail running shoe.
