Technically improved from the inside, out. As On's flagship hiking boot, the Cloudrock 2 Waterproof has a new precision hiking fit with a Missiongrip™ rubber sole for better control and traction, in any conditions. For hikers and outdoor explorers everywhere, updated Cloud elements, added heel stability and a reinforced collar give a more secure fit and comfortable ride from sun up to sun down. While underfoot, the closed midsole channel means you can leave the trail, on the trail.
