I bought these specifically for my work in surgery because the rubbery toe box looked great for a bloody environment. They are absolutely great for that! They are so easy to wipe clean at the end of my shifts. However I found them to be kind of stifling for the feet due to lack of breathability and ...my feet sweated a lot. I bought moisture wicking socks for them specifically. They are also very wide in the toe box, which for someone with a wide foot is great, but for someone like me with an average width foot did kind of make me feel like I was wearing flippers. The moisture wicking socks helped because they are rather bulky and filled up some of the excess space in the shoe. These shoes are CRAZY comfortable. I wore them for 22 hours straight while stuck at work for a complicated surgery and although every inch of my body hurt after that, my feet didn't! I am keeping these, but I'm not sure if I'll repurchase them yet, we'll see how they age. That said, if Crocs started selling the insoles from these separately I would buy pairs by the dozen.
