I wear size 11.5 usually sometimes 12 very rarely 12.5inch - I got the pair thats supposed to be for up to 12 (I think) and they are way too tight, inflexible, and the frabic is not pleasant on the skin

"I wear size 11.5 usually sometimes 12 very rarely 12.5inch - I got the pair thats supposed to be for up to 12 (I think) and they are way too tight, inflexible, and the frabic is not pleasant on the skin. As far as work socks go that wont tear, sure, but for every day socks unless i get a bigger pair which until now i disregarded and still doubt i will try, i think im okay on $20 socks lol"
