So now the advantages: the real sheepskin boots is the "heat-regulating", so you get no heat accumulation. Aussies wear Emus without socks, but is not recommended for the black, because you get black feet ;-) Another goodie of Emu boots are removable insoles which can be exchanged later. The boots have become a waterproof impregnation, which one should renew a season. (Caution: not waterproof !!) For the size I had no problems. I bought the size I wear otherwise. However, one should consider when buying that the boot wide, so never buy bigger.
The Emu Stinger can really combine to many. That's why I can recommend buying.
