I recommend sizing down.
Purchased in INTGRN/FROYEL/BROYAL
I read the reviews about sizing down before ordering. My normal shoe size is a 10 and that's all they had left in stock, so thats what I ordered. I don't think they're as oversized as the other reviews claim. A 9.5 would have fit, but your feet swell when you run so I'm very happy with my purchase. These are the most comfortable shoes I've ever owned and need no break in time!

These are probably the most comfortable shoes I've ever put on my feet! But they run huge. Thankfully I read the reviews and went down a size. I probably could've done another 1/2 size down. But super cute shoes - overall very happy with the purchase.

So far, so good. My only complaint is the arches. I have high arches and I wish there was better arch support.
I’m usually a size 8 after reading reviews I sized up 1/2 size and I’m happy I did.

Very pretty shoe, but like the other reviewer said, sizing is way off. They run big and I would size down a whole number size if I were you. I had to return my initial order.

Gorgeous shoe but sizing is running big. I run in my sneakers so I usually buy a ½ size bigger but these were extremely long. For reference, I wear a 10 in nike for running and 9 ½ in regular Adidas Ultra Boost. I wear a Size 9 in these Stella McCartney Ultra Boost. I would also note that the weave on this shoe is similar to a summer shoe, very breathable.
