Nike, Cons, Adidas and Vans are at least part to blame for Cariuma's success.
These brands have either, stopped opening accounts, closed accounts, or screwed over accounts.
Footwear sales are super important to skate shops and shops are now being "forced" to carry what ever brands will open them.
Cariuma has definitely done a better job at marketing to today's skate consumer that Etnies, Es, Emerica, State, DC, or Lakia and thus I understand shops wanting to carry the brand.
