RuffWear Boot/Shoe Liner Socks set of 4 Set of 4 dog boot/shoe liner socks in black and grey. All four have 2.0/2.25 printed on the inside (fits these size dog boots from RuffWear). My dog wore them once (with the boots) and was not fond of them, though they were the right size for her. 🤷‍♀️ Smoke-free home!
