Why mess with a good thing? To make it even better. That's what Vasque did with the new-and-improved St. Elias FG GTX Hiking Boot. Not only do these boots have comfort upgrades like the All Terrain Compound (A.T.C.) midsole which combines a TPU shank with foam cushion pods, they also cut weight to make their most lightweight boot even lighter. While the A.T.C. midsole gives backpackers athletic flexibility and even more comfort, the new rubber toe-cap protects the foot from rocky terrain or those tree roots that seem to pop up out of nowhere.
