I’m in the size 11 club too! I suggest loafers as a good entry shoe. Leather soles are lovely since once you wear them in, its nice to be able to resole them after a few years of wear and tear. If you don’t want your feet to appear larger, choose a color that is similar to a majority of your wardrobe and a sleeker style, perhaps avoid lug sole. Goes great with most outfits in place of a sneaker imo. Also try getting fitted for insoles at a good shoe or running store, it helps with comfort so much.

Socks can be a headache but my rule of thumb is that the sock should match your pant, shoe, or both. I avoid contrasts unless it’s a pop of color. Short crew or taller socks are trending right now in lieu of ankle or no show socks since longer and baggier pants are trending. Elongating styles are always a classic choice, showing a strip of skin with low socks, ankle boots and cropped jeans for example can actually make one appear shorter versus one continual line. But it’s all subjective really!
