I ordered these in a 10 C/D and then in a 9.5 C/D but neither fit quite right. Just an overview of my feet, in case you are considering these sandals. I have a very high arch and instep, so the extra long straps across the instep were not a problem for me. But I also have bunions, and the front strap on only one shoe cut into the bunion just enough to be uncomfortable. However, they have a very comfortable cushioned footbed, which made me think twice before sending back. Hope this helps in your consideration of this model of Clarks shoes.
