Normally wear an 8. 5 but I stuck to my gut and ordered half a size up , got a size 9, glad I did bc the 8. 5 would’ve definitely been uncomfortable. Not wide feet friendly fyi, more comfortable for narrow feet, and if my calves were any bigger they would not fit lol but they are just right for me. Order half a size up for sure, don’t wear thick socks either , will be uncomfortable, it would be for me at least.
