The Ruffwear Grip Trex dog boots set the standard in paw wear for dogs who hike, bike, run, or explore the great outdoors with their humans. These high-performance boots feature a rugged and resilient Ruffwear-designed Vibram outsole for exceptional grip. Breathable mesh upper keeps dirt and debris out while keeping them cool and comfortable. The closure system combines hook-and-loop with hardware and cinches around the narrowest part of the dog's leg, providing a secure fit so they can forge ahead with confidence. Available in sets of 2 boots and 4 boots. Just as you would with your own gear, check the closure system and adjust the fit as needed 15 minutes into your activity and throughout the adventure. Washing instructions: Secure fasteners, wash in cold water with mild detergent on a gentle cycle, and air dry.
