I tried them on once, but they're in great condition, so I think they can still be used for a long time. They're very cute boots with fluffy details. Thank you. [Rubber soles]: Anti-slip effect, making it less likely to slip on slippery surfaces such as flooring. Prevents floor scratches from claws. Protects the dog's paws from dirt and injuries from glass or other objects on the road. [Easy to put on and take off]: Zipper + Velcro. Wide opening, easy to put on. No worries about them coming off during walks, and they won't easily come off even with vigorous movements like jumping or running. [Prevents dermatitis, wounds, and worsening inflammation]: If the paw is injured, it prevents the dog from licking the wound and making it worse!! #DogShoes
