We have created five-toed socks with a firm texture, knitted with 100% linen on the inside and 100% strong cotton on the outside. If you like linen, we hope you will try these five-toed socks with a crisp linen pile. They are a unisex free size with no heel. Linen has just the right amount of heat retention, so they can be used all year round, not just in summer. Please see the product page for details.
