I bought the brand ones. They are absolutely worth it. The fake ones don’t even compare to that level of comfort.
I’m tried them and while I didn’t notice a big difference I can believe that there’s a difference. I personally don’t consider it worth it though when Crocs start at 30€ and generic clogs can be less than 5€. But with those quality varies a lot, so buyer beware. I’ve just very rarely seen people buy the branded ones is what I meant with my original post
