Nike Dunk sizing is pretty simple, Dunks and SB Dunks (for men and women) both fit true to size. However, they aren’t the comfiest pair of shoes on offer from Nike – which can be off-putting if you're planning to wear your Dunks constantly. If you have wide feet, you'll also want to try Dunks on before buying as we can tell you firsthand that our Nike SB Dunk High Chicken & Waffles are a bit snug on wide feet.
