These boots are really nice. Very roomy in the ankle area, so perfect if you have thick calves and are trying to do boots without them looking tight. I wear a size 8 1/2 or a 9 depending on the shoe. The other reviews were said they ran big, then some said they were the perfect size, and others that they were tight. Actually here's the actual run down, the left shoe as mentioned in a couple reviews is a tiny bit snugger. The ankle area is roomy if you have smaller ankles and a narrow foot these will be really really roomy for you. The toe box is average. I have a wide flat foot and still went with a 8 1/2 still fit still feel decent. If I wanted to wear regular socks verses my thin no show socks I would go a size up. I'm thinking of getting them in black and go up to a 9 to compare.<br />Giving them a 4 verses the 5 only cause the lefty was a tad smaller. (A smidge) the good thing is even with that tiny defect I think they'll stretch out and be fine after a couple wears.
