The Cloudventure 3 Waterproof Running Shoe in Ice/Kelp from On Running.

The lightweight waterproof trail running shoe with extreme cushioning and grip. Mountains beware.

• The Missiongrip outsole combines multiple grip patterns so you keep control on the trail in changeable conditions. Own the downhill with the unrivaled cushioning of Zero Gravity Cloud elements. Strategically placed heel clouds absorb impact on inclines. Steep just got softer.
• The advanced On membrane is 100% waterproof, yet still lets your feet breathe for climb-crushing comfort. It's also highly stretchable, so you can move freely and comfortably over uneven ground. The elastic loop on the tongue keeps your lace ends from trailing over wet ground or becoming a trip hazard.
• You can't outrun the rain, especially in the mountains. We made the Cloudventure Waterproof for trail runners who won't let the elements mess with their off-road missions. It's low on weight yet big on cushioning and grip. Plus, the Swiss-engineered Speedboard ensures wet weather doesn't dampen your pace. Narrower at the midfoot for added torsion, it lets your foot flow over rocky terrain.
