Greetings fellow flipper Friend! I wear a 6E in Dunham brand boots, and for general sneakers / "running" (gym) shoes i wear a brand called "xelero". New balance makes exactly one 6e width shoe IIRC, the 990 i think? It used to come in multiple colors but now just the one color if its a wide shoe.
If it helps, I'm also stuck with very thick feet so my picks also account for that. Center of my sole to top of foot is 3 inches.
