River Wear's "Northern Comfort" line of slipper socks are slip-resistant, thanks to the ABS knobs on the soles. ABS is a tougher, temperature resistant synthetic.
These slippers are great for:
Long naps during winter months, camping and sleeping out in the wilderness, warming your paws when it's cold outside, lounging around the house.
Also available in 'I love my dog' slipper sock
