The Aventrail R2T Shoe swaps laces for a FuseLock hook-and-loop closure built with twice the strength of a standard strap, so it locks down fast and stays locked down mile after mile. A HYPER-COMF+ dual-density midsole cushions every step without weighing the shoe down, and an engineered bootie construction wraps the foot in a sock-like fit that needs no break-in. It moves easily between everyday road miles and the packed dirt and loose gravel of an easy trail day. What Our Gearhead(R) Experts Are Saying:"I've taken these past the pavement onto rockier trail sections on the same run, and the Spider Rubber Endure outsole keeps grabbing even as the ground gets looser underfoot. That kind of range is what turns a run into a hike without a shoe change, since the lugs hold up whether I'm on packed dirt or scrambling over loose rock."
