The Croloose liners are made from very-spun silk, offering a soft, near-silk finish that reduces abrasion and feels gentle throughout the day. Because they are very thin, they function as a barely-there layer that still protects feet from direct contact with shoe interiors.
These silk liners use natural moisture-wicking properties typical of fine silk to move light perspiration away from skin, helping feet feel drier than bare contact with shoes. They’re best used as an inner layer below thicker socks when you expect moderate activity or as a daily liner in casual shoes.
Croloose silk liners are designed for easy home care: machine wash with like colors and tumble dry on low. The pair tolerates occasional non-chlorine bleach when needed, and because silk is delicate, avoid ironing to preserve fiber integrity and shape.
This set contains four pairs—two black and two white—sized to fit men's 6–8.5 and women's 7–9.5. The sizing aims to provide a snug, hug-like fit that stays in place inside shoes without bunching.
Q: Can I wear these silk liners alone in sneakers?
A: Yes, they can be worn alone in low-profile sneakers, but they’re best for light activity or as an inner layer under thicker socks for rigorous use.
Q: Are these liners machine washable?
A: Yes, machine wash with like colors, tumble dry low, and avoid ironing; non-chlorine bleach is acceptable sparingly.
