What if I'm in between sizes?

Size down for a tighter feel, or up for more comfort—especially if you're new to compression. You can also email with any questions or concerns regarding sizing.

Do Comrad socks fit wide calves?

Yes! We make wide calf sizes in many of our knee-high styles. If your calf circumference is over 17", measured at the widest part of your calf, we recommend choosing one of our wide-calf-friendly options for the best fit and feel.

Why do some of my socks feel tighter than others?

Several factors can affect how tight a pair of socks feels, even if they're the same size and compression level:

  • Compression Level: Our Knee-High Socks come in both 15–20 mmHg (moderate) and 20–30 mmHg (firm) compression. Higher compression will naturally feel tighter.
  • Fabric & Knit: Different materials (like cotton vs. nylon) and knit constructions can affect stretch and snugness.
  • Wear & Wash History: Over time, compression socks may stretch slightly with wear—or feel tighter right after washing and air-drying.
