Narrow with low instep -
When these arrived, I thought they looked small - I checked the box to be sure. They were size 9, as ordered, but I can't even get my foot into them... they are VERY narrow and the instep is VERY low, so if you have arches at all, you may have trouble. Also, they are of pretty poor quality for the price. The "fuzzy pile" innersole didn't even fit into the shoe - it buckled along the side at the heel. I should have stuck with
Acorn - they have always been great
slippers for me.
