Despite the name "summit walker", I can't recommend these for mountain climbing. The shoe soles are much flexier than real mountaineering boots, which can make them uncomfortable and unstable on rocky terrain. For walking on easy trails and pavement, they are fine. These boots are wider than many other lightweight boots, which improves stability as well as giving you room for wider feet. I like that the laces extended all the way down to the toe so you can really tighten them if you want. The paper-thin insoles is pretty worthless; I replaced them with padded insoles instead. The heel cup is nicely designed and keeps your foot from sliding around in the boot and causing blisters. The zipper feature doesn't work very well, especially if you have thick socks. I think these boots would be better without the zipper and with a faster lacing system instead. These are fine light hiking boots when the price drops below $40. Above that, and there are plenty of better options.
