I'm a solid 7.5 in shoes. I ordered these espadrilles in a 38 as recommended by the size chart, but they were too big length/width-wise. Returned, and ordered them again in a 37, and they fit much better. I feel like a half size would have been perfect, but these only come in whole sizes. Either way, I recommend sizing down if you are a half size. I have an average (maybe ever so slightly narrow) width foot for reference. Sizing issues aside, I do really like these. The footbed is nicely padded and comfortable. The 80cm (3.5 inch) height seems to be fine for wearing for longer periods of time.
