Love these- was looking for an alternative after I literally wore the soles out of another pair of sheepskin slippers. The robust soles on these should mean they last even longer.
I’m a size 5/38 and the M are fine, they are very full at the moment because of the pile being new but that will flatten out over time. I tried the L and they were way too big.
The higher outlay means they are more cost effective as they will powers lots of cheaper slippers.
