Short answer
Dunk Lows and Highs fit true to size for most people, according to The Sole Supplier, Stadium Goods and Laced. SB Dunks feel snugger because of the padded tongue; Sole Retriever suggests half a size up for wide feet or thick socks. Women: your men’s size is your women’s size minus 1.5.

How to pick your size
Measure in the evening
Feet swell during the day. Measure heel to longest toe in inches, both feet, and use the longer one.
Match the chart
Find your foot length in the table above. Between two rows, take the larger.
Adjust for width and model
Wide feet, thick socks or an SB Dunk: consider half a size up.
Check the label
Confirm the listing is men’s, women’s or kids sizing. Women’s and GS listings use different numbers for the same foot.
Kids sizes are on kids blue Dunks; women’s conversion detail on blue Dunks for women.

Questions people ask
Should I size up in Dunks?
Not usually. Stay true to size unless your feet are wide, you wear thick socks, or you are buying an SB Dunk and like room. Then half a size up.
Do Dunks fit like Air Force 1s?
The sizing guides we cite cover Dunks, not other models. If you own both, go by the Dunk advice here and your foot length rather than assuming your other size carries over.
Do Dunks stretch?
Leather uppers soften and give a little across the width with wear. Length does not change, so do not buy short expecting them to stretch.
How do I measure my foot?
Stand on paper with your heel against a wall, mark the tip of your longest toe, and measure heel to mark in inches. Match it to the foot length column in Nike’s chart.
