Super cute!!!
I normally wear a 10W. I have a very high instep which makes most of the cute slip-ons a little too narrow, and they aggravate the bunion on my left foot. Those also have no support whatsoever.
I could not believe how comfortable these are right out of the box. The wiggle room for my toes is amazing. They do slip on the back of my heel without socks, but I think a liner will help that, and I think a 9.5 would've been too snug. The bottoms are not slippery on my wood laminate flooring, either. I can't attest to their durability as I just got them, but I will report back if they don't hold up.
