There may be some confusion with the double-sizing of Heschung. They print two sizes on the box : Euro and US (1/2 size difference). We list the US sizes on our website to try to eliminate some of the confusion. I believe that on a US size basis, you sized down 1/2 a size. If you look at your box, it probably says "Eur 8 US 8.5" On a comparable US basis, most people get their usual US size or size down 1/2 for that boot.
