its really hard to come up with a new shoe that people will actually buy. Most skaters wear vulc vans/emerica/janoski style shoes and quite frankly nike and vans have it covered. People are over the innovative athletic style shoes of the nineties/early 00's (which i grew up on and really miss personally).
If you go on filament, state's website right now they are making shoes identical to the ones the top brands make (check for yourself), shoes with the likeness to the Chima shoe, janoski, vans era, huf shoes etc. I get why they do this, theyre being giving the market what they want, but your gonna be really hard pressed to compete with the big corpos and pry people away from what they know and trust in these big companies.
I feel the best way to get a shoe brand of ground and get skaters buying is to have a really interesting team that does shit a little bit different and looks a lil bit different i.e Magenta & Isle. they both have really interesting styles and each dude brings something different to the table. where as Filament and states teams have greats skaters but theyre just vanilla no mike Arnold level dudes
