After reading previous buyers reviews I ordered half size smaller, and I probably should've ordered the whole size smaller. Although with thick sock they would be OK. The quality of leather is very high, I was very pleased to get it for that low price. The calf is probably 17"-17.5", they are a little bit too wide to wear them with nylons and skirt, but definitely OK to wear with jeans tucked in. All in all I would definitely recommend to buy them - just buy 1 size smaller!
