these boots are true to size but if you have wide feet BEWARE they are extremely narrow!!!!! I went based off the reviews and got a size 10 which is my normal shoe size thinking the shoes run big. my feet are a size 10 but I usually get a size 11 if the shoes run small. they are the perfect length but if you have wide feet u better not buy and you can not return these boots it is final sale!!!! if u have thick calf’s good luck the boots will not zip up. I suggest you go up a size if u buy these boots
