Catering Shoes Success.
I randomly found nuusols on the clearance rack while on vacation when my Chacos died after 10 years of service and have been wearing them since. I'm easily able to get 15000 steps with no pain.
When I started a catering job, I bought the standard non slip shoes but couldn't make it the entire night. Switched to black croc style of nuusols and can make it through even the 20K+ step shifts. Haven't had an issue with slippage.
