Genuinely work to keep feet much warmer. Bravo!

Yes, I recommend this

These are brilliant. Really effective at genuinely keeping feet much warmer than normal or even thick socks. Worth the money and ideal for Winter. Nice quality feel, soft. Quite long, so come up high on the leg - but who cares, as they work to keep feet toasty not frozen.

EXCPETIONAL QUALITY, REALLY WARM

Yes, I recommend this

There are really good!! They keep my feet really warm. I went out in 0 degree weather with nothing but these socks and mules on and didn’t feel a thing. (Oh by the way, it was my first time in a country that experiences winter and temperatures like this, as I’m from a tropical country, so that says A LOT!!!)

Warm and snug but shrunk a little after washing

No, I don't recommend this

Very comfortable and warm but after several washes they have begun to shrink. Purposely did not tumble dry in case this happened as it seems to with most socks. Slightly disappointing.
