Not 100% true. Not everyone wants to spend crazy money for every article of clothing they wear just because they wear expensive shoes.
Yes and no to that, N&F denim ranges from $100-$180. Most of the people in here have multiple pairs of shoes that they don't get to wear all the time on a consistent basis. To me I'd rather spend that money on a decent pair of pants that I'll get way more uses out of, especially with having a job where you can't always wear sneakers. I do agree a lot of people don't want to spend that money on clothes but personally I think it's a better choice in the long run. Expensive denim to me is anything over $300.
