Inspired by Karl Melzter, 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.
Often called Clifton for the trail, CHALLENGER ATR 4 looks even more like a Clifton with its cleaner, less busy look and more breathable upper. And like the Clifton 4, Challenger ATR 4 is fast and light, offering a smooth, smooth ride. Where it diverges from the Clifton and takes the path less traveled is in its multi-lugged outsole. Arranged closer together towards the heel for a smoother, more consistent ride, its lugs have a wider spread in the forefoot to help with grip on the trail and in wet conditions. Still as versatile and supportive no matter the running surface, Challenger ATR 4 has improved upper durability in the areas you need it (like a larger toe guard area). Let’s take to the trails people!
