Adjustable strap for a secure fit. Grippy tread bottom for traction on walks. Top holes allow for proper ventilation. Can handle active walks and runs. Comfy and breathable for your furbaby. Be the envy of the dog park with the BARK Dog Crocs, designed specifically for dogs. These EVA foam booties are not only stylish, but also comfy and breathable for your furry friend. Just like human Crocs, these booties can handle active walks and runs, thanks to their adjustable strap, grippy tread bottom and top holes for ventilation. So grab the leash, throw on these Crocs, and show off your paw-sh pup. My boy tried these on once. They are like new!!!
