I love love love these boots!  They fit very well, make my feet look tiny and are sooo comfortable.  The heel is great and it doesn't even feel like i'm wearing any type of heel.  I followed the advice of other posters and ordered a half size larger.  I wear an 8.5 so I ordered a 9; when I opened the box, the box was a 9 but the boots inside were 8.5.  I tried them and they fit perfectly, plus after about wearing them 2 times they loosened up a bit.  I do however wear thinner socks (trouser socks), so if you prefer to wear thicker tube socks you should order a half size larger.  Otherwise I would stick to your true size.  These are so great, i'm about to order 2 other pairs from Jump.
