Sizing guide
Compression is sized by your leg, not your shoe. Two minutes with a soft tape measure, in the morning, is all it takes. Between sizes? Choose the larger one.

How to measure
Measure in the morning
Legs swell during the day, so measure soon after you get up.
Sit with your foot flat
Sit on a sturdy chair, knee bent at a right angle, foot flat on the floor. A helper makes this easier.
Calf: the widest part
Wrap a soft tape around the fullest part of your calf, usually a hand-width below the back of the knee.
Ankle: the narrowest part
Measure just above the ankle bone, where the leg is narrowest.
Thigh, for thigh-highs
Standing, measure around the upper thigh about 2 inches below the buttock fold.
Snug, not tight
The tape should lie flat without pressing in. Measure both legs and use the larger numbers.
Well-fitting compression feels snug but never painful. Take it off if you notice numbness, tingling, a change in skin colour or pain, and check the size.

Sizing questions
What size compression socks do I need?
Size by the widest part of your calf, not your shoe. For our zipper socks: M 8-11 inches, L 11-13 inches, XL 13-16 inches, 2XL 16-18 inches, 3XL 18-20 inches. For other socks, email us your calf and ankle measurements.
What if I am between sizes?
Choose the larger size. A sock that is too tight at the top band digs in and rolls down; one size up still gives graduated compression.
My calf is over 20 inches. What fits?
Our wide-calf zipper socks run 4XL to 7XL and our firm knee-high runs to 7XL. Email us your calf and ankle measurements and we will tell you which size.
Can I exchange for a different size?
Yes. Tell us within 30 days of delivery and we send the right size, with a free US return label.
