Best for Cross-Training

Crescent Moon Rocket Carbon-Fiber Showshoe

The carbon-fiber frames of the Rocket gave snow runners a stable deck, with just enough flex to help push their stride into high gear. The direct-mount, binding-free option weighs a mere 1.1 pounds and includes the hardware to attach a pair of running shoes directly to the Rocket's deck. The slightly heavier model (still only 1.42 pounds each) features gel-strap bindings that never loosened mid-run in testing. [$449;]
