Thickness and Length
Pairs of socks come in all sorts of thickness and lengths. On each product page you will find a thickness and length indicator.
The blue outline will indicate to you what sort of thickness your socks will be. As you can see from the example, these socks will be fairly light. The heaviest socks in terms of thickness, would be say winter wool socks, where you can expect maximum warmth for cold days, or hard wearing, for example, an outdoor work sock.
The totally blue filled image indicates the length of the sock. The highest socks we do are over-the-knee. Within the example image, you will notice, these socks are knee-high.
