The draw: Feather-light power
Jan Frodeno’s customizable shoe of choice, the golf ball-like Zero+ shoes almost look like incomplete prototypes. The dimpled upper is stitched straight into the carbon fiber soles, and there’s no visible cushioning. But they provided the best power transfer of any shoes tested and the most natural foot shape. Stiff arch support may aggravate prominent navicular bones, but it also prevents pronation to keep knees in line. They’re not tri-specific, though, so they’re best used for longer races when a few extra seconds to put them on and take them off won’t cost you a podium.
