Pillow Paws Single-Imprint Terries Slipper Socks provide warmth, comfort and peace of mind with the tread on the bottom. The quality and comfort of our terry knit socks make them the most wearable patient footwear products in the industry. Unlike other manufacturers, the slip-resistant tread is printed on the smooth side of the terrycloth fabric. This allows the ink to puff and create a full, robust tread design. The ink is not lost in the terry loops, enhancing safety and comfort. Our Pillow Paws Terries Slipper Socks are machine washable for multiple usages.
