Cold and wet weather hiking calls for a fully featured boot to keep us going. The Adidas Terrex Leather Mid Cut Rain. Rdy Cold. R Boot is one of our favorite hiking boots for fall and winter due to its insulated and waterproof design. The Rain. Rdy membrane ensures our feet stay dry and comfortable all day, while the 200 grams of Primaloft synthetic insulation keeps our feet warm and happy. They are topped off with a lightweight EVA midsole for support and cushion, and the Continental Super High Traxion Rubber outsole provides reliable grip in all conditions.
