The crocs are GREAT, but I had two issues: 1) They are too narrow. I purchased Width 'M', but as my feet are swollen I had to slit the top crown of the shoes about 2&#34; for my feet to be able to slide inside. I'm thinking that a wider size (if it were available) might have been better, and 2) The available adjustable-length of the heel straps are too short)
