The Merrell Women's All Out Blaze Mid Waterproof Hiking Boot handles long trails in wet or sunny conditions. M Select Dry equips this boot with reliable waterproof and breathable protection for winter hikes and the shoulder seasons' wet days, and the mesh lining ensures ventilated airflow in summer's warm weather. Merrell made the boot's upper out of oily leather for long lasting durability, and TPU reinforcements prevent the heel from breaking loose. Underfoot, Merrell inserted its innovative UniFly midsole for surprising flexibility, mobility, and responsive cushioning. Omni Fit's lacing system gives a snug fit from toe to heel, and the bellows tongue keeps debris out of the boot. The All Out Blaze also features reliable Vibram rubber at the sole for season after season strength.
