The award-winning Superior is back! This already popular shoe was such a hit in the reinforced 3.0 version that Altra added even more durability in the upper as well as a 4-Point GaiterTrapTM system. If you love the lightly cushioned, speedy Superior with its tough DuraTread outsole and sleek profile you'll love the 3.5 more than ever. Ideal for trail running, ultrarunning, trail racing, fast packing.
