Do monochrome grey sneakers exist? I can't find any.

The only ones I've seen are old collabs that are either completely out of stock everywhere, or absurdly expensive.

New Balance is the king of grey. 530, 550, 2002r, 1906, 9060 etc. probably all have what you're looking for.

If you're okay with minimalist leather sneakers, Thursday, Koio and Oliver Cabell have some.

Out now
