Super cool boot-the KEY is to buy it 2 full sizes bigger than your normal shoe size. This is not like the bulky round toe slip on Ugg boots that run big. This is a close fitting more shoe-like boot.  So if you want them to fit big enough to wiggle your toes and go barefoot inside of the shearling lining  this worked out great for me. Im a size 9, normally buy 9.5-10 in boots so I can wear socks or tights; bought these in 11.
