• 43-45: 2 stripes
• 46-48: 3 stripes

Sized according to European shoe sizes, with corresponding common S, M, L etc. sizes in brackets. See the chart below for further reference:

Simple size | EU size | US shoe size | UK shoe size

X-Small | 34-36 | US 2½-4½ | UK 2-4

The sock shrinks about 10% in the first wash. This is accounted for in the sizing.

Material 64% merino wool, 36% polyamide. The polyamide is added to the mix to wear resistance; you can march countless miles before wearing these out. 

The joys of merino wool

Merino wool is moisture-wicking, quick-drying, and self-rinsing. It's also machine-washable, but washing is usually unnecessary - wool cleans itself. These qualities make merino wool clothes superb for outdoor use. Oh, did we also mention how good they feel against your skin?

And oh yes, this stuff is mulesing-free!

Made in Finland.

Want to know where the merino wool comes from?

Our sock provider Sukkamestarit has joined the NATIVA™system, the purpose of which is to be able to trace the merino wool back to individual sheep farms. Because of this, you will also be able to find out where the wool for all our merino wool Särmä socks comes from.

From August 2020, the packages of new Särmä socks got a QR code that you can use to trace the source of the merino wool.

Wash and care

Machine wash at 40° C / 104° F, when needed. Wool cycle recommended. Air dry. Don't leave them in a wet lump after washing. Reshape them gently while still damp.

When not in use, a good shake and airing outside will magically cleanse the wool. You only need to wash merino wool if you see stains or the clothing starts to smell really bad. This usually requires lots of continuous use without airing.
