Also came to vouch for the MiUSA line of NB stuff. Can't go wrong with a 991-993, or 990v1-6, especially in that OG grey. They are pricey since they're made domestically but it's definitely worth it.
The 990v5 is my daily driver off board and it's real comfy/supportive. Can always find a good deal on those resell sites already mentioned, but they also come out with so many colorways lately that they end up on sale often on boutique sites like Bodega, Concepts, Packer, etc especially with BF around the corner.
