I love the metallic iridescent!
Why did you pick this product vs others?: I love the color and the feel but the sizing is wonky. I’m a perfect 7.5. The 7 wears like a 6-6.5 and the 8 is just a little too big. I’m keeping my 7 in the blue and I have a pair in wine/purple in 8 from a few years ago. I just won’t be running a mile in them anytime soon! LOL I love the look!

Comfortable and good traction
After being impressed by a similar (but not identical) pair of cheap slippers at an AirBnB rental, I searched out these. I bought the 44-45 size for my size 10.5 (US) feet; according to the size chart, that's supposed to fit sizes 10.5 to 11. I find that they're quite large, so that they're loose on my bare feet. In crew socks, they're OK and I use them as house slippers. As advertised, they're soft, flexible, and springy. They grip the floor quite well. They're way better than the Crocs thong-style sandals I was using as bathroom sandals before. All in all, good value for money, but if you're using them as bathroom slippers and you have normal width feet, round the size down if you're at the small end of the stated range.
