Shimano MT22 is my favorite. Discontinued a few years ago. Mine have so far has lasted 5 years of being worn every single workday, are far from worn out. Fine to work and walk in, pretty low profile look. I even bought a backup pair too. New ones come up occasionally on eBay, not terribly expensive. For example (no relation to seller):
