Compression socks only do their job if they fit properly. Too loose and you get no support; too tight and they're uncomfortable — or worse. Here's a simple, no-nonsense guide to getting the fit right.
What "right" feels like
A good compression sock should feel firm and supportive, like a steady hug around the foot, arch and ankle — never painful, pinching or numbing. It's snug everywhere, with the most noticeable support around the arch and ankle, easing off slightly higher up.
You should be able to wear them for a full training session and forget they're there. If you're constantly aware of them, the fit is off.
Quick check: is the fit right?
- ✅ Just right — a firm, even hug; you forget you're wearing them
- ❌ Too tight — tingling, numbness, throbbing or deep marks → size up
- ❌ Too loose — bunching, sliding, twisting, no real "hold" → size down
Signs they're too tight
- Pins and needles, numbness or tingling
- Skin that's marked deeply or discoloured after taking them off
- Pain rather than gentle pressure
- Difficulty getting them on at all
Signs they're too loose
- The fabric bunches, wrinkles or slides down
- No real sense of support or "hold"
- The sock twists around your foot during activity
A loose sock isn't just ineffective — a wrinkling sock causes friction, which causes blisters.
How tight for running vs recovery vs travel
The right feel is the same everywhere — supportive, never numbing — but the context helps:
- Running: you want a secure, no-slip hold so the sock moves with your foot through every stride. Snug is good; numb toes are not.
- Recovery after a hard session: a firm, even hug over the arch and calf is what helps you feel fresh — still comfortable enough to relax in.
- Long flights or desk days: the same steady, comfortable pressure; if your feet swell, loosen or take them off rather than push through pins-and-needles.
If a sock only feels right standing still but bites when you move, the fit — not the activity — is the problem.
How to get your size right
- Measure your foot length (heel to longest toe) and check it against the brand's size chart rather than guessing from your usual shoe size. Our size guide is here.
- Check both feet — pick the size that fits the larger one if they differ.
- Don't size down for "more compression." Compression comes from the knit design, not from squeezing into a smaller size.
- When you're between sizes, follow the brand's guidance for your foot length.
Getting the size right matters even more if you have flat feet or fallen arches, where the arch support does the most work.
Putting them on the easy way
Roll the sock down to the heel, slip your foot in, then unroll it up the leg — don't yank from the top. Smooth out any wrinkles so the pressure is even. (How the compression and grip are built →)
Frequently Asked Questions
How tight should compression socks be?
Firm and supportive — like a steady hug around the foot and ankle — but never painful, pinching or causing numbness. Snug everywhere, with the most support around the arch and ankle.
How tight should compression socks be for running?
Secure enough that the sock stays put and moves with your foot through every stride — no sliding or twisting — while staying comfortable. You should never get numb toes or throbbing; if you do, size up.
How tight is too tight?
If you get tingling, numbness, throbbing, or deep skin marks that don't fade quickly, they're too tight. Compression should feel like even pressure, not a tourniquet — go up a size.
Should compression socks leave marks on your legs?
A light, temporary line where the cuff sits is normal. Deep, angry marks or indentations that linger mean the fit is too tight — size up, or choose a sock with a wider, softer top band.
How do I know my compression sock size?
Measure your foot length from heel to longest toe and match it to the brand's size chart, rather than relying on shoe size. If your feet differ, size for the larger foot.
Should I size down for more compression?
No. Compression comes from the knit, not from a smaller size. Sizing down just causes discomfort and poor fit. Choose the size that matches your foot length.
