I cannot be more pleased with these crocs. I purchased these because of the reviews and even considered to upgrade at the time, and I'm glad I did with this shoe.  Coincidentally, I got these shoes 2 weeks before I had my knee surgery and I am extremely satisfied with them.  I did buy them one size up from my normal size and it should be ok for you as well.  Thanks to the interchangeable strap, these shoes feel snug even at a larger size.  I refuse to put these shoes to rest and they have helped me tremendously.  The style is classy and the comfort is exceptional.  I occasionally have swelling on my feet and these shoes help me feel comfortable by not having pressure on the swelling area.
I did spray some leather protector on the top sole and they still look new.  I thought I would limit them to just household wearing, but I am now using them at work and people don't see anything weird about them.  The comfort and convenience is awesome!!  Go get them.
