I love those white and red croc Nikes, but as much as I like the grey colourway, I'm not convinced suede is a good choice for footwear outers.
It marks and damages easily, and is hard to clean and imperfections in the surface show up really quickly. If you've got any raw denim, it'll eat up the indigo and stain heavily.
Common Projects have some nice grey low and mid tops in leather, I think they do a high top as well, but I couldn't find a picture in all leather.
Have you looked at Kim Jones for Umbro's high tops, vulcanised with leather?
There's something about the front/toes of those that looks very strange to me(they look too long??)..
Also I need a lot of support around my ankles cause my feet are like mega flat.
I see what you're saying about the support. Dior homme have done some killer high tops in seasons past (not sure about currently), but they're even more expensive than the Common Projects.
Have you played around with the Nike Id tool online?
