These were my second pair. 1st ones lasted a couple years till they were worn out. This pair didn't make it a whole year till the souls started coming off. Little over a year and they completely feel apart in pieces. They were only used about 15 hours a week when i needed slip resistant shoes. They would have only lasted 2 months if i had worn them 40 hours a week. They are very comfortable and helped me get rid of my plantar fasciitis with my 1st pair and didn't come back with these(w/extra heal memory foam. They just went super cheap on the adhesive..
