I have used CROCS BISTRO's for a long while now and love them. However, the last two times i ordered them, I had to have them replaced, because they where not slip resistent at all. This never happened before and the replacement shoes worked perfect. I hope that the ones I have replaced this time will work just as well. If not I will have to look for alternatives. I wish CROCS would test them to identify the problem. Dispite the fact that Crocs has replaced the defective shoes both times without question and where very helpfull. At this time I would not recommend these Crocs for a professional kitchen or wet invironment.
