“Graduated compression” shows up on every compression sock label, but it’s not always clear what it actually means. Here’s the plain-English version — and why it’s the whole idea behind how a good compression sock works.
Firmest at the ankle, gentler up the leg
Graduated compression means the sock is snuggest at your ankle and gradually eases as it goes up your calf. That gradient is the point. It gently encourages circulation upward, which is what helps your legs feel fresher and less tired at the end of a long day on your feet.
What the numbers mean
Compression is measured in millimeters of mercury — you’ll see it written as mmHg, usually as a range like 15–20 or 20–30. A lower range is a lighter, everyday feel; a higher range is firmer support. There’s no single “best” number — it depends on what you’re using them for and how they feel on you. If you have a medical condition, your doctor can point you to the right level.
Getting the fit right
Compression only works when the sock fits. Too big and you lose the gradient; too small and it’s just uncomfortable. Check the size chart against your shoe size and calf, and give the sock a chance to break in — a good pair should feel supportive, not pinching.
The SmoothToe difference
Every SmoothToe sock is built on a graduated knit with our signature smooth toe — no bulky seam to rub — and made in the USA to hold its shape and its compression wash after wash.
