The One is Altra’s lightest weight shoe, which makes it suited for both racing and tempo running and, perhaps for some, even daily training. Round 3 continues with the versatility of its predecessors, while adding some nifty new aesthetics. The upper is a closed mesh with full-length, thin, fused overlays from the foot-shaped toe box to the heel, and anchored with a stiffer synthetic suede below the Achilles tendon tab.The medial side of the tongue is tacked in place both for a bit of support and to keep
it from slipping side to side. The eyelets are segmented to allow articulation with the foot’s movement. While spare, the ankle padding is sufficient to protect and conform to the foot. The midsole is single-density A-bound foam shaped by the Altra’s zero-drop geometry. The outersole is toughened foam with A drop-in blown rubber component called FootPod, that provides traction and additional durability. The result is a light, fast- feeling shoe that handles well the duties on the quick end of the running spectrum.
Testers: ”Roomy forefoot with a light, fast feel. Good cushion, great flexibility, no problem with traction. Great for faster runs.”
