It's a very generic shape. Loaded started out making flexy boards, from bamboo, aiming at the more casual cruising/carving/dancing market.
They've recently released some stiffer boards, more focused on downhill and slides.
I'm honestly just talking about logo design and color. The Boosted board is from Loaded.
I fail to see similarities between boosted's logo and e-go's logo. They are so incredibly different. E-go's logo looks more similar to ubuntu's logo, so one could argue that boosted borrowed their style from ubuntu?
