Feel great, size down
"I'm a 9. 5 and I bought a 9 which I usually do with booties, other booties I'm happy only going down half size because others are more narrow, but these fit more true to their actual size and have nice space in the toes, they have a bit more room, so I wish I went down a whole size to an 8. There super stretchy and feel really comfortable, easy to get on and off without the strap too, not having a strap in the way of your suit is nice, and it's not needed with the flexibility of these. They feel great, just go down a whole size in my opinion."
