When the trail is more mud than dirt, and there's more rain in the forecast, we trust the KEEN Targhee IV Mid WP Hiking Boot to keep our feet dry and stable over slippery terrain. The KEEN. DRY waterproof membrane repels mud and water as we pick our way across ruts and roots, keeping our socks dry the entire way. The KEEN. RUGGED sole provides excellent traction, giving us excellent grip as we scramble over wet rocks, and the heel capture system and stability shank keep our foot secure so we can trust each step on our way to the summit.
