I generally fear to buy shoes or clothing online as sizing is inconsistent. One needs to read the reviews to make sure this isn't a problem. And with this pair, it wasn't. A perfect fit. If you plan to wear socks regulary with these you should buy a larger size, but who wears socks with slippers? I suppose some do. I never have. If you're going to go to all the trouble of putting on socks, might as well go the step further and put on shoes as well. These seem to be exceptionally well-made and I expect them to last a good, long while.
