Sizing for compression is all about knowing your calf circumference. Carefully measure your calf - at its widest part - using a fabric measuring tape. Lily Trotters can really stretch, so to ensure your calf feels the 15-20 mmHg hug accurately, select the size that matches your calf circumference.
Many people can wear both sizes comfortably. The majority of our product testers found the S/M to be the right size. Our socks do stretch everywhere, so keep that in mind. If you are on the taller side, you may prefer the length of our L/XL. Remember, Lily Trotters are 100% Satisfaction Guaranteed. Follow our Returns & Exchanges policy if your socks do not fit and we will help guide you to the correct size.
