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
I do realize. I've only ever seen knockoffs until I bought myself a pair. The cost is a lot different, but considering the quality and durability, I think they are worth it. I often say, that I can't afford cheap things. The shoe theory comes to mind. Literally XD
