I can wear a Size 8, but normally wear an 8-1/2 shoe now because I find that size much more comfortable.

In this boot, I ordered down to a Size 8 and, with the Shearling and regular thin socks, the fit is perfect.  I have to tug on the back loop to get it on my foot, but I have no problem with the size other than that.

I also bought some tall Emu boots and really regret it.  I can stomp through any high snow in my crocs, go for a 45-minute walk in very cold weather, and my feet are warm and comfortable.  But that kind of walking with my Emu's is too hard, as they are rather loose around the ankles.  So, I use my Crocs boots, which are short, and my pants get covered with snow.

Do I buy yet another pair of boots?  If so, it will be tall Croc's boots, size 8.
