Personally, I’ve always had good luck with any of the “surf brands” flip flops. My personal preference right now is billabong.

I can’t stand the way the super cheap, like from Walmart or target, ones feel anyhow.

Also, some people swear by Birkenstocks. And east coasters seem to love some Teva ( I’d never be caught dead in them or crocs or Birkenstocks for that matter).
