fuccboi is just generally somebody that has no awareness in a certain field yet think they do -
so girls may define a fuccboi as a guy that straight up asks for nudes, as he has no female experience yet still acts cocky
/fa/ defines a fuccboi as somebody that dresses up in old hype clothing, things that peaked on popularity last year and are now only worn by people who think they're cool.
in essence Roshes are outplayed and dead, they were a meme piece that lived fast and died young and now everybody and their gran owns a pair.
Also yours are in an awful colour (bright scarlet red is not necessarily a bad colour, but it's hard to incorporate in an outfit, and seeing as you're asking for advice on what to wear your Roshes with, let alone thinking they're still relevant shows that you probably won't pull them off well).
In my opinion you should:
 lurk more (spend more time browsing the board to get a feel for fashion)
 Perform some DIY on those Roshes if you feel competent enough to make them easier to wear or more interesting (Dye/fade colour to something less loud, add modifications)
 Sell them and use the money to save for some nicer shoes.
Check out the sticky if it still works, surf some WAYWT threads or try find an /fa/ infographic on google images.
I match my roshe run with straight fit line pants, here is a picture
