Croc bistro all the way. I Go through about a pair a year. The backless design is great to keep you cooler, and they are very comfortable. A huge tip: no matter what shoe you buy, go to a podiatrist and get properly fitted for an insole. plantar fasciitis is a very coom problem for people who are on their feet all day, and it's not fun. The insoles usually last for a very long time (I've had mine for three years.) Well worth the $100 I spent for the insoles. Also, wearing non slip shoes on asphalt will wear them much faster then normal kitchen wear, so I always bring something else to wear when I'm not working. Even a short walk to the car will take it's toll.
And if you buy shoes and they are uncomfortable and you can't return them, throw them out. Eat the money you spent and get a new pair. Its not worth $100 to have sore feet every day.
