As wide as any shoe we’ve ever seen, this medically-approved therapeutic oxford comes in a super XXW width called 6E by its maker Orthofeet, but it will fit even wider feet, especially if you remove one or two of the fitting spacers beneath the customized insole. Designed for people with diabetes, the shoe is soft, padded and non-binding with seam-free linings and a cushioning ergonomic sole. Men's sizes 7–12, 13, 14, 15 in XW(4E) and XXW(6E).
