Dog shoes, size 3. I tried them on indoors, but my dog wouldn't wear them at all, so they're practically unused. The following is a quote from the official website: Easy-to-wear dog boots that protect your dog's paws from snow, salt, mud, and sharp terrain. Each set comes with four boots. Water-resistant exterior, soft microfleece lining Double Velcro straps and toggles to secure the shoes during walks Protection from snow, salt, sharp terrain, mud, and harmful chemicals Durable rubber PVC sole for grip and protection Wide opening, easy to put on and take off Reflective straps for nighttime safety
