Merrell's best-selling women’s trail running shoe just got bigger and better in the Antora 3 Mid Waterproof. Key updates to this boot include a more durable upper for over foot protection, a softer and more responsive midsole with FloatPro Foam™ pods strategically placed under the heel and forefoot where you need extra cushion the most, and a new grip-enhancing design to the outsole made by Merrell's partners at Vibram®.
