Removable Liner by Soxsols Black Wool
Soxsols footbed liners are reusable inserts for footwear. They prevent sweat from being absorbed into the footbed, provide comfort and a snug, cushioned fit and are machine washable. They really work! We wear them in shoes, boots, clogs and our sandals.
They come in both wool and cotton versions. The bottoms are super grippy to keep them from sliding around in your shoes.
