Size guide
Sock size guide
Shoe sizes aren’t consistent between brands, and it’s your foot that has to fit. Four sizes cover UK 3 to UK 14.
The sizes
The four sizes
The same measurements appear in the size guide that opens over the buy widget. They are read from one place, so the two cannot disagree.
| Band | Foot length | UK | EU | US |
|---|---|---|---|---|
| S | 22.0 - 24.0 cm | UK 3-5 | EU 36-38 | US 4-6 |
| M | 24.5 - 26.5 cm | UK 6-8 | EU 39-42 | US 6.5-9 |
| L | 27.0 - 29.0 cm | UK 9-11 | EU 43-46 | US 9.5-12 |
| XL | 29.5 - 32.0 cm | UK 12-14 | EU 47-49 | US 12.5-14.5 |
How to measure
How to measure and choose
How to measure
Stand on a sheet of paper with your heel against a wall, mark where your longest toe ends, and measure from the wall to the mark. Do it in the afternoon — feet are slightly bigger later in the day.
Between two sizes
Take the bigger one. These are a close, stretchy fit, and going down grips your toes and shortens the life of the waterproof layer.
Measure both feet
Most people have one foot slightly bigger than the other. Size to the bigger one. It’s a small thing and it’s why a lot of socks feel right on one foot and tight on the other.
In boots and cycling shoes
They’re about the bulk of a mid-weight sock. Snug walking boots and race-fit cycling shoes are where that matters most — the use-case pages cover each of them.

What if I’m between two sizes?
Take the bigger one. A sock that grips across your toes is uncomfortable over a full day and puts constant tension on the waterproof layer. The fit is stretchy enough that the bigger size won’t feel loose.
Are the sizes the same for everyone?
Yes. One range from UK 3 to 14, set by foot length rather than a men’s or women’s scale. Take the size your measurement falls into and ignore the label you’re used to.
Do they fit the same as my normal socks?
Closer. They’re shaped rather than loose-knit, so they feel more fitted at the same nominal size. That’s deliberate — it’s what keeps them in place.
