Sock Sizes

The critical consideration when buying socks is to get the correct foot length.   Sock lengths are usually given by reference to shoe size, but to get a more accurate measure you can stand on a ruler, and measure the longest part of your foot in centimeters.

Most Humphrey Law socks for adults are made in small, medium and large foot sizes.  Details of these appear below but broadly speaking :

the SMALL size fits the average ladies’ foot, or a men’s small foot;

the MEDIUM size fits the average men’s foot, or a ladies’ large foot; and

the LARGE size fits the men’s large foot.

Details of sizing for children’s socks, extra wide socks, and Ankle Foot Orthotic (AFO) socks are also listed below, and are followed by details about the (leg) length of socks.

Extra Large Socks

As noted above, sock sizes are usually quoted in terms of foot length. However

Extra large feet are likely to be wider or more bulky as well as longer. As socks are a knitted fabric, when they are stretched width-ways the sock necessarily becomes shorter. This often makes it difficult for someone with extra large feet to find the most comfortable sock for them.

Humphrey Law knit socks with extra width in the following sizes. If you have larger feet and are unsure which sock will be best for you, feel free to send us an email including details of the width and length of your foot, the circumference around the heel, and around the lower leg. We will then suggest the likely best size sock for you.

Leg Lengths

The length of a sock is measured on the leg, from the floor to the top of the sock. Measuring the length of a sock as it sits on-the-shelf will not produce an accurate result. The “relaxed” shelf leg length varies according to the amount of lycra in the sock, the thickness of the sock and the time it has sat on the shelf.
Most socks – with a “C” as the third character in the full Style code – have leg lengths around 18 to 22cm (Ladies’) or around 22 to 26cm (men’s) depending on their contents.
Our men’s half-hose socks have a leg length of 45cm which means that they come to just below the knee, they are Styles 11H and 31H. The ladies Style 86H is 40cm long.
The cotton walk sock has considerable stretch and while it can look short on the shelf its leg length when worn is 45cm.
Mid-calf socks are about 35cm long. They are Style 31F and Style 22H.
Ankle sports socks (Style 36A and 57A) have a 3cm leg. And the cushion-sole sports socks (Styles 33A, 33B, 47A and 47B) have a 10 to 12 cm leg.
