Seems like a good product but did not fit. Runs small.

They work for spa shoes, but they run a little big. I am keeping them anyway.

I wear 7-7.5 in US sizes and 37 in Birks. I ordered the 39-40 size and they fit my feet perfectly length-wise, but the shape around the pinky toe joint feels a little weird. Like, it doesn't widen like other shoes (like birks) do. The shoes are still comfortable, though, and I wear these as house slippers. I needed something opened toed and breathable and not fabric so my cat wouldn't rip it up.

It hurts a little after standing in them for a while, but overall work well.

Cool and comfy
