Fit tips
Between sizes?
Size down for a firmer feel, or size up for more comfort — especially if you're new to compression.
Wide calves?
Measure at the widest part of your calf. If your measurement is above the listed range, the fit may feel too tight.
Why can one style feel tighter than another?
- Compression level: higher compression may feel tighter.
- Fabric & knit: different materials and constructions can affect stretch and snugness.
- Wear & wash: socks may feel tighter after washing and relax slightly with wear.
Calf guidance applies to knee-high compression styles only.
