With the Grip Trex, those paws can go the distance thanks to the rugged and resilient Ruffwear-designed Vibram outsole with exceptional traction and protection on varied terrain. Breathable mesh upper provides ventilation, and the closure system combines hook-and-loop with hardware, cinching around the narrowest part of the dog’s leg to provide a secure fit. Items come from a non-smoking home with old lady dogs, with sneaky white hair! We're selling items to help support senior dog rescue in Colorado. Funds from this sale, will go to help old dogs, get the care they need and find a loving forever.
