Wide toe box
People with arthritis
in their feet typically need a wide toe box in their shoes.
The toe box is the end of the shoe where your toes are. Many manufacturers are making wide shoes these days. For gym shoes, new balance, asics and nike all make wide width shoes. In dress shoes, dunham is particularly good; their shoes go up to 6e. For socks, i recommend a sock that wicks sweat-target makes cheap.
