Flat feet put extra outward pressure on the big toe joint, which is part of why bunions and flat feet so often show up in the same person. These picks give the joint room without giving up arch support.
A genuinely wide, rounded toe box that doesn't taper sharply toward the big toe, which matters more for bunion comfort than almost any other single design feature.
Anyone whose bunion pain is aggravated by any snugness across the forefoot.
People needing firm, structured arch support above all else.

Combines a genuine wide-width option with real arch support, which matters since a bunion-friendly toe box alone doesn't solve the flat-foot half of the problem.
Anyone needing both bunion room and genuine arch support in one shoe.
Anyone wanting a lightweight athletic shoe over a supportive daily one.

The adjustable straps let you fully customize where pressure sits across the forefoot, which is useful for a bunion that's uncomfortable with any fixed structure pressing on it.
Warmer climates or casual settings where an open sandal is practical.
Anyone needing closed-toe protection or firm structured support.

A bunion forms when the big toe joint is pushed outward over time, and a collapsed arch changes how weight travels across the forefoot in a way that increases exactly that kind of pressure. It's not the only cause of bunions — genetics and footwear history both play a role — but flat feet are a well-documented contributing factor, which is why treating the two together, rather than picking shoes for one and hoping the other works out, tends to give better results.
The core tension is that shoes built for aggressive arch support often use a more structured, narrower last through the forefoot, while shoes built for bunion comfort often skip real arch support entirely. The picks above were chosen specifically because they don't force that trade-off.
The right shoes can meaningfully reduce pain and may slow how quickly a mild bunion worsens, but they generally can't reverse an existing bunion deformity. For a severe or worsening bunion, a podiatrist consultation is worth having alongside footwear changes.
Often yes, specifically at the forefoot. A bunion pushes the big toe joint outward, which can need extra width right at that point even if the rest of your foot measures as standard width.
Not universally, but an adjustable sandal like the Birkenstock Arizona can be more comfortable for some people because you control exactly where the straps sit relative to the bunion. Closed shoes with a wide, rounded toe box work well too, and offer more protection.
