The On icon for all-day performance made fully waterproof. For urban adventures in all conditions. Zero-Gravity foam and CloudTec® in the outsole provide soft landings. Advanced abrasion pads ensure superior grip, while the molded heel provides a snug, secure fit. The Speedboard® within transforms the energy generated as your foot lands into forward motion. The signature speed-lacing system allows your foot to slip in and out with ease, yet keeps the shoe firmly in place on the move. Jesse Brown's recommends sizing up in the waterproof.
