After 20 years of buying socks I can tell you that you shouldn't buy low cost socks, unless they are good quality. i used to have like 50 pairs of socks and most of them made my feet sweaty and uncomfortable. Now I have like only 10 pairs of socks but they are all really good quality and my feet are happy and comfortable all year round!
My advice, go to a discount shop like TK Maxx or Ross and buy the best socks they have for a cheap price. "Stance" make some really comfy, good quality socks, I also have some nice thick Adidas and Nike socks. The Nike basketball ones are real nice.
