Collection: Women's Organic Cotton Socks 70-100% — comfortable socks in 70-100% organic cotton Organic cotton (70–80%).

Socks made with 70–80% organic cotton

Our socks are cotton-led: thirteen styles made with 70–80% organic cotton, each with at least 18% recycled polyamide and a little elastane. Crew, knee-high, ribbed and tennis lengths all sit here, and the blend barely changes between them.

Is there a 100% cotton sock?

No, and there is no style on this page above 80% cotton. The rest of each pair is at least 18% recycled polyamide, with elastane, because a sock has to stretch over the heel and come back to shape. Cotton on its own does not do that.

The lengths

The Core Crew Socks are the standard pair, with ribbed, logo and butterfly-ribbed versions of the same length. The Core Stripe Knee High Socks are the longest. The Active Tennis Socks are the sport pair. Each product page carries the exact cotton figure for that style.

Sizes and colors

Sizes are 35-38, 39-42 and 43-46 rather than single numbers, so one size covers several shoe sizes. Thirty colors run across the thirteen styles.
