The Otomo Katsuhiro 'Steamboy OST' Dunk is treated by the sneaker community as a concept/custom design with authenticity debate ('legit or not'), so buyers should not assume it corresponds to an official Nike retail release.

This is a blue SB Dunk Low listed under the Otomo Katsuhiro "Steamboy OST" concept, which the sneaker community treats as a custom design rather than a confirmed official release. Sizing guidance below comes from general Dunk and SB Dunk discussion, not from this pair. Confirm the colorway and your size before ordering.

Pros
- · Wide listed size run spanning roughly 36 to 46, with half sizes in the middle of the range.
- · Community discussion of Otomo Katsuhiro colorways describes suede uppers as clean and well-done — a colorway-family remark, not a check on this pair.
- · SB Dunk Low construction is discussed as having extra padding and tongue straps compared with regular Dunks.
Cons
- · The "Steamboy OST" design is treated in community discussion as a concept/custom with an open "legit or not" debate, so it should not be assumed to be an official Nike retail release.
Fit notes
Nike's Dunk sizing guidance and general buyer feedback say Dunks run true to size. Community consensus adds that SB Dunk Lows carry extra padding and tongue straps, so wider-footed buyers are often advised to go up half a size. Neither source tested this pair.
