Our winter walks and hikes just got a whole lot better with the Merrell Speed Strike 2 Thermo Mid WP Boot. Our regular winter boots aren't made for hiking, but the Speed Strike Thermo combines athletic performance with a fleece lining and synthetic insulation to keep our feet warm as we take on snowy trails and sidewalks. These boots are 100% waterproof with grippy outsoles for slick, wintry surfaces, keeping us comfortable and upright when we extend our hiking season into the coldest months of the year.
