Product review from a busy RN who works 12 hr shifts and has gone through more shoes than I can count: This rank near the top of the best shoes I have ever worn to work.

Pros:
-Almost all mesh, so very breathable, in fact at the beginning of the shift my feet are even cold sometimes. I love this. Hate sweaty feet.
-Comfortable, lots of cushioning
-Looks pretty cool

Cons:
-Sizing is off, I wear a 10, sometimes 9 1/2. I ordered down based on reviews to a 9 1/2. Should have gotten a 9 or 8 1/2.
-Not a very secure heel. This might be due to the sizing issue, but I think even with a tighter fit the heel still sits low compared to Saucony or Ryka.

Also I should mention these will not stop body fluids from touching your feet- last Sunday I had an iv come loose on a heparin drip and then I dropped the soaked bloody gauze on my shoe- thank goodness it hit the one part near the laces that is vinyl and I was able to scrub them down with disinfectant.

Overall I think I will put these in rotation with my Saucony pair, and might buy another pair in a smaller size as I have less hip pain since I've been wearing them.
