I love these shoes!  I bought Iron and even though its a strange color, I actually like the color.  Not quite gray but in the ballpark.  This shoe ran small for me.  I am a true 7.5.  Every pair of shoes I own is a 7.5  The size running small has nothing to do with the fur insulation.  Its the length of the actual shoe itself.  I have returned them and ordered an 8.5 so that if I want to wear thick socks or no socks it will be a perfect fit.  I used the size chart and pulled out a ruler to figure out how much longer I want them.  Going up a half size doesn't really do anything for this shoe especially if you break down the actual measurements.
I wasn't expecting the entire inside of the shoe to be fully lined with the fur so that was a nice surprise.  There is a strange seam on the inside of the shoe right where your big toe goes as I think another poster mentioned.  Could be part of the reason I felt my toe was smushed at the end.  This will be a really warm, cozy shoe for the winter and is a cute, stylish clog that will look fantastic with my jeans.  Overall, this is exactly what I was looking for and I am happy with my purchase and how easy it was to exchange them with Amazon for a larger size.
