Altra Lone Peak 9+ review

The Lone Peak 9+ suits a specific runner: one who wants a flat, zero-drop platform and as much toe room as possible. Altra lists a 0 mm heel to toe drop and a 25 mm stack, which it classes as mid cushion, so it feels closer to the ground than the Topo, Saucony and Merrell shoes. The 9+ moves to a Vibram Megagrip outsole for grip on wet and dry surfaces, and a lighter Altra EGO midsole. The Original FootShape fit is Altra's roomiest, with space for toes and through the midfoot. A StoneGuard sits underfoot for protection on rocks and debris, and the GaiterTrap tab lets a gaiter attach without straps. The upper is a no-sew ripstop mesh made from recycled polyester for durability. At 11.55 oz it is one of the heavier shoes here, and the moderate cushioning makes it less suited to runners who want plush foam. Altra also sells a GTX version for $180 and the older Lone Peak 9 for $145.
