I’m a true 10 and followed the reviews and sized up and 11 fits perfectly with no room to spare - 10 would’ve been too small for sure. They’re very pretty and look way more expensive than they are. They are a little less sturdy than a good quality shoe. I’ve only tried in the house, I bought for an event next month. I think they’ll be perfect for the night and don’t need them to last longer but if they do, I’ll be happy. They do look gorgeous.
