The best to analyze whether the shoes are slip-resistant or not is to verify that the soles are made of durable and slip-resistant rubber and embedded with grooves or lugs in a particular pattern. The slip-resistant soles are mostly made of rubber or nitrile material. In my article of best shoes for factory work, I have reviewed the 22 best shoes regarding their comfort, safety and slip-resistant. You will see that all the shoes have a sturdy design and have rubber soles with thicker lugs for high slip resistance. Similarly, in my other article of best shoes for nurses, I have reviewed both casual and sporty style work shoes that the nurses, chefs, and restaurant workers can wear to provide an excellent slip-resistant.
