The Grip Trex dog boots set the standard in paw wear for dogs who hike, bike, run, or explore the great outdoors with their humans. 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. It&';s a good idea to check the closure system and adjust fit as needed 15 minutes into your activity and throughout the adventure. Note- this is a set of TWO boots. Many dogs have wider front paws than rear paws. Ruffwear offers their boots in sets of two so you can order the appropriate sizes for a good fit on both the front and rear paws.
