[Looking for the latest version? The women's On Cloud 5 Waterproof is available now.] See those rain clouds rolling in? Don’t let them ruin your run. The Cloud Waterproof takes On Running’s most popular Cloud running shoe and seals it against the gnarliest weather. On uses specially engineered mesh in the upper to keep the rain and wind out of your boots, and a step-in heel loop makes slipping into them a breeze. Like the original Cloud, the Waterproof uses On’s unique cloud elements in the midsole to cushion your ride, but the all-black shoe is painted with reflective details to make you visible at night—or under the thickest cloud cover.
