You have totally missed the point of a shoelace belt. Skateboarders wear it for functionality not style it doesn't feel very comfortable having a real belt digging in your side while bending down for pop. True some belts feel better than others, but it does not compare to a shoelace belt.
People not being lazy or trying to be cool while wearing a shoelace belt example REAL skateboarders.
shoelace belt is used by skateboarders for comfort and better support. Rather than having a thick belt that digs into your hip when bending down or when you fall from doing a set (also tear a lot faster, even if belt is leather) you wear a shoelace belt. Also, shoelaces can be tied to a comfort that isn't gained from a normal belt.
Extra shoelaces are received when you buy skate shoe's cause we tear are laces a lot. They can be used as belts, but most shop's that sell skateboarding pants sell them with shoelace belts (i.e why they are designed by skateboarders).
