A pretty snug medium, the Pinnacle Pro fits especially close at the instep, ankle, and navicular bone, testers said. The toe box is wide. It's surprisingly strong on edge given its lightweight all-Pebax construction. Testers hammered it all over and couldn't ever push it to edge-grip failure, though a few of the heavier testers thought that the flex maxed out under heavy loads. The hike mechanism offers a huge range of motion and is smooth both fore and aft. Astle: "An awesome, athletic boot."
