If you’re browsing wide-sized walking shoes, first confirm through measurement that you actually need spacious footwear. “A shoe that is wide has more space in the heel and middle foot (midfoot),” says Milica McDowell, DPT, a physical therapist and vice president of operations at Gait Happens. “This is different than a regular width shoe with a wide toe box, or a more natural-foot shaped shoe.”

Ideally, if you do indeed have wide feet, you’ll want a shoe that is wide sized and has a wide toe box, Dr. McDowell says. Keep in mind the nomenclature: Shoe widths are typically designated with a B (regular), N (narrow), or, for most brands, D (wide), according to Dr. McDowell.

Another key word is “straight-lasted,” which basically means a shoe was crafted with a wider foundation to accommodate a wide foot, says Roach. Some manufacturers may specify that their shoes were built on a straight last, but if not, you can tell by simply peeping the bottom of the shoe: It will look boxy and symmetrical instead of curving in at the toe box.

Beyond that, prioritize wide shoes made with flexible material for the uppers–like knit mesh, or soft leather, for example. This allows the shoe to conform to the shape of your foot minimizes the risk of calluses and blisters, Roach explains. Bailey echoes a similar sentiment, recommending shoes made with leather, breathable fabrics, polyurethane, Ethylene Vinyl Acetate (EVA) and elastic components. “These materials not only accommodate wider feet but also ensure a spacious fit and exceptional all-day comfort,” she says.
