Thin ski socks

depends on what is available in the UK versus in the US, so you might get some different answers on brands but whatever is the thinnest, non-cotton sock.

Brands that I am aware of are Smart Wool Ultra Light PhD, Darn Tough Ultra Light... just get something that is similar to a dress sock in thickness.

would football (soccer in america) sock work ?

If they're cotton, I'd say no. Invest in some good socks, like Smart Wool, that have good moisture-wicking properties and are thin.

smartwool for sure. make sure it's the kind that's thin but has padding where you need it. they make a sock that is thicker on the shin and specific parts of the foot and it's easily the best ski sock I've ever worn.

I just buy cheap knee high girl socks, they're thin(a must) and you can get 3 for a couple bucks. plus they have awesome rainbow leopard print and shit.

i mainly use Under Armour like baseball/soccer socks. They're long, thin, in hella different colors, and comfy. They are fairly breathable and last me through a winter (about 80 days). they keep my feet dry just like when i used to wear them playing ball. the cheap sports socks that are real thick on bottom always got holes in them after a week or two. i also own a bunch of Smartwool "ski" socks, made for just for skiing (at least what manufacturer says). They're warmer, about as thin but with more material around heel and toes, but no better (imo) for keepin your feet dry at the end of day, and for me they start to get worn quickly around the heel and toe areas. Not exactly sure but at like a big 5/sporting good store a pair of under armour sell for around $10/pair compared to Smartwool $20/pair.

I always use hiking liner socks. They're super thin because they're designed to be worn under other socks but have all the moisture-wicking abilities you want in socks you're going to be active in all day. I've got some Wigwam ones right now but most hiking brands would work. They also have the benefit of being less than half the price of most ski socks.

Eastern Collective has some really good ones in my opinion

Bridgedale Micro-fit or Ultra-fit. Super thin and awesome. The only skis socks I'll wear.
