RUGGED: Tough waterproof anti slip sole provides stability and traction, protection from sharp thorns, hot pavement and asphalt in the summer, salt and snow during the cold winter months. QUALITY: Our shoes have a rugged sole and high quality fabrics that are then sewn together (not glued like cheaper dog boots) to ensure they are ready for your adventure. Easy to put on / off. The shoe expands with a wide split seam opening and two adjustable and reflective fastening straps to ensure a tight and secure fit.
