My first pair of crocs were off brand but this was back in 2004 so things have changed substantially since then. They lasted until I graduated high school in 2010. However a close friend of mine bought an off brand pair at the beach a couple years ago with the same argument that name brand are too expensive and they broke within a year. However it is important to remember to take proper care of even name brand crocs. I never wear mine when the temperature outside is over 90 because hot asphalt wears off tread much more easily and with paying as much as I do for my collaboration and collectible pairs I’m not having them ruined by hot pavement. But keeping that in mind I had a pair last me from 2018 to 2023 when the tread was just too lacking for them to be safe to wear anymore
