Altra’s inaugural midcut fastpacking shoe weighs just .4 ounce more than the original lowcut version, yet the added ankle support was substantial on rocky, washed-out scrambles up and down Colorado’s Middle Boulder Creek. The waterproof, zero-drop shoe is great for ultralighters putting in big miles, thanks to a wide toebox (great for trail swell) and extra cushion in the maximalist outsole. $160; 1 lb. 8 oz. per pair
