I missed out on the Yeezy Slides but this is very close in terms of comfort. The foam is just as comfortable as the foam runners and great for recovery. I'm a size 9 and bought size 9 don't regret it. The reason why people go size down is because it looks big is due to the sides rounding up making it look bigger but with socks it's the perfect fit of loose/secure. My friend is a size 10 bought a 9 and it was a bit tight and small. I think if you try to tip over to the side you can fall down so be careful.
