And a relief to my old bony feet on the hard floor of the shower. The instep strap isn’t snug enough but that’s because of my very flat feet not having a high enough profile to grip it. Should be perfect for normal feet.

These shower shoes are the only reason I haven't felt the need to dip my feet in bleach after I shower. 10/10 no bleach required (although they are a bit small, but I may have just ordered them a little small by accident. Not like these are to be worn for long periods of time)

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.
