Actually, it's two boots, not one. I am using my boyfriend's profile here. I looked at the men's sizes instead of the women's when ordering my boots and my feet are swimming in them! They are size 42 EU, or US mens 8 to 8-1/2 or US women's 9-1/2 to 10. I've worn them a few times, because I thought I was going to make them work, but my feet are just too small. They retail for over $150, but you can get them for a steal if you want a like new boot, only worn by a girl who has not done much riding... YET!!!
The link below will take you to a pair of black Set Up boots. My boots are black with blue on the shin (couldn't find a web pic with blue). Don't miss out on an excellent pair of boots for $100 or best offer.
