The MTL Long Sky 2 Matryx is a race shoe, and it ranks last here only because our angle asks for cushioning as well as grip. On grip it is one of the strongest shoes on the list: Merrell fits a Vibram Megagrip outsole with 5 mm lugs and rates it for rugged trails with heavy debris and frequent changes of speed and direction. It is also the lightest shoe here at 8.29 oz per shoe. The upper is a single layer of Matryx fabric that combines Kevlar and high-tenacity polyamide threads, which Merrell says breathes better, stretches less and resists abrasion. FloatPro foam and an ETPU footbed provide the cushioning, but the stack is only 23.5 mm at the heel and 19.5 mm at the forefoot, with a 4 mm drop. Merrell says its athletes have raced it on major trail podiums. At $170, runners who want comfort over long training miles get more foam for less from the Agility Peak 6.

Who it is for

Racers and fast mountain runners who want maximum grip and low weight more than deep cushioning.
