Shoes for Crews has got to be the best non slip footwear on the market. If you work in an industry where you are around slippery floors, these are the shoes for you, my husband swears by these shoes, he has been wearing them for 6 yrs now, and will not wear any other shoes. He has not yet ever slipped with these shoes on, and he is a truck driver so he is in and out of restaurant and up and down the back ramp on his truck, even on the the most terrible days of rain and ice he hasn't slipped.
They are well made rugged waterproof Nubuck leather, with a removable insole, the bottom sole is guaranteed to be slip resistant. They have styles for both men and women, they have clogs, athletic, steel toe, casual, dress and Work boots. These are a must have for that extra little bit of safety.
The only downfall is they only have one store and it's in Las Vegas, so all purchases have to be made online unless of course you live in Las Vegas. But even with that they are well worth it.
If you order you have 60 days to wear your shoes if you don't like them, they will either exchange or refund your money. But trust me you will be happy.
