The sizing info on this boot is very confusing and I was at a loss as to what to do.  What I found is that if you are a half size, you should order down in size.  I am a 7.5 and ordered a size 8 which was a great IMMEDIATE fit.  However, this boot is going to stretch ALOT so eventually my size 8 became too big - I have remedied that with thick socks (but they are still a little large).  Then recently I ordered a size 7 in this boot and found that they initially fit snug but very soon after, stretch out to accommodate my foot very well.

I own both EMUs and UGGS and it is in my estimation that EMUs are superior to UGGs.  I love this boot - it is thicker and warmer and the support in the sole is so comfortable.  They are also less slippery in snow than UGGs and the pricing is perfect. I will wear these forever!
