These are so comfortable and cute! They fit *just* right- I think a 1/2 size up would be too large, but as a sandal type shoe it works okay being bang on in sizing. Here's the most ringing endorsement I can give: wore these to a wedding and didn't need to change into flats or take these off all night, no problems walking with a couple glasses of wine on board, looked stylish enough to suit the occasion. Doesn't get much better!
