I already had a pair of big, bulky rain boots and I wanted something less bulky and a little more stylish. I loved these on Amazon and purchased them in red, size 6. The foot part fits nicely, around the ankle and lower half  of calf are fine but the top forget it! I don't have huge calves, that black trim at the top cuts off my circulation and I can't wear these boots for long. Unfortunately I realized this as I was wearing them during Hurricane Sandy clean up so I can't return them. I thought about modifying them (cut the top off haha). The top shouldn't be so constricting and it was hard to tuck pants into them as I do with my other rain boots. Over all, they are pretty, stylish, true to color as advertised and true to size but I would recommend maybe ordering a size up maybe the opening will fit better.
