Designed with enhanced durability and comfort, KEEN® Targhee IV Mid Waterproof Boots are made with waterproof leather and recycled poly mesh – complete with a waterproof membrane that lets feet breathe but keeps moisture out.The Luftcell midsole absorbs shock with approximately 100,000 air bubbles per cubic centimeter as you pound through field or fen. Reinforced lacing tabs lend a secure fit, plus a TPU outsole that’s twice as rugged as standard rubber soles. Now that’s a feat of foot-friendly engineering!
