Query: Great shoes at an unbeatable price, but watch the size!

Seibel delivers--these shoes are as comfortable as they are beautiful. At Amazon's great price, anyone can afford a pair! A word of caution though: They run at least one (if not one and a half) size SMALL, so order up! Being from Europe, I know European sizes well, and I'm a 37.5 or 38, but I had to get a 39 in these. (The size chart conversion is very confusing and seems to vary with each store or site, but in my experience a 38 is a US size 8.)
