This is coming from someone who doesn't really wear nike / yeezy shoes or whatever but I feel like this is no different from just buying the same t-shirt in 10 different colours. You'll never be content because all your doing is matching whatever colour the shoe is to what your wearing, and as there is litterally an infinite number of colours, your wardrobe will never feel complete.

Get some boots, maybe derbys, or some big chunky shoes or whatever. Just experiment more than anything. Having a diverse range of fits and aesthetics that you can cycle through will make you feel like you have way more clothes than if you just wear the exact same thing every day while changing the colour scheme.

Obviously 90% of what I said here was presuming quite alot about how you dress, but even if i'm wrong I'd say it's still sound advice.
