I bought the size 10, and could not even get my foot all the way through. I do have wide feet but I wonder if a size 11 would work (too bad there is not one).

I got these in red-very very cute! I wanted a snazzy wedge/slide for my upcoming trip to the bahamas, and these definitely fit the bill. Beware; they have a narrow footbed! I have fairly narrow feet, and my arches hang over the side a little bit. The front straps are not too narrow, though, and the material is soft. These are also very slippery. I will need to put the non-slip pads on them. Over than that, these are absolutely worth the price. I will probably wear them until they fall apart.
