Long days trekking or pedaling steep, rocky terrain in stiff, supportive footwear demand a lighter, more comfortable shoe to wear around camp. Problem is, even compact, lightweight options like flip-flops take up a lot of precious pack space and add weight, making them more of a luxury, less of a must-pack staple. Zpacks' fully collapsible 2-oz Camp Shoes are one of the best solutions, but their heel-cord form isn't for everyone.
