Nike SB Dunk Low
Sizing & fit guide
Two ways to fit it
For a snug, board-feel skate fit (or a suede toe box / recent general release) stay true to size. For casual all-day comfort — especially leather pairs and heavily-padded collabs — size up ½, since the skate padding makes them run small.

Why the Nike SB Dunk Low fits this way
Unlike the regular Nike Dunk Low (which fits true to size), the SB Dunk Low carries a thick padded tongue, a Zoom-cushioned insole, and reinforced skate padding that eats into the interior volume. The dominant recommendation is to size up a half: "I go ½ up in SB Dunk Lows. All the padding makes them tight." The most useful nuance comes from a skater-vs-casual split: "if you're a skater and you're going to thrash them, go TTS; if you're buying for casual wear, ½ size up — the extra padding tends to make them run small." Skaters want the snug, board-feel fit and accept the tightness; casual wearers want comfort and go up.
Material is a real variable. One wearer's rule of thumb — "TTS if suede toebox, ½ up if leather" — reflects that suede gives and conforms while leather stays stiff and tight. Several commenters also note SB Dunks run narrower than the AJ1: a US 13 SB Dunk Low Pro buyer felt the sides pressing on the midfoot more than their US 13 AJ1 Low.
Fit also drifts by release: "Recent SB Dunks have been fitting me TTS compared to previous ones like Habibi's or Born & Raised, where I absolutely had to go up half a size." So newer general releases trend closer to TTS, while heavily-padded collabs run smaller. Net: ½ up for casual comfort and leather pairs; TTS for skating, suede toe boxes, and recent GRs.
Common scenarios
I wear US 10 in regular Nike Dunk Low. What size SB Dunk Low?
US 10.5 for casual wear — the SB's extra padding runs about ½ small. If you skate and want the snug board feel, US 10 (TTS) is fine.
Should I size up for a leather SB Dunk?
Yes — the rule of thumb is TTS for suede toe boxes, ½ up for leather, since leather stays stiff and tight while suede conforms.
How does the SB Dunk Low compare to the regular Dunk Low?
The regular Dunk Low fits TTS; the SB runs about ½ smaller due to skate padding. If you're TTS in regular Dunks, go ½ up for SBs (casual) or stay TTS (skating).
How does the SB Dunk Low compare to the AJ1?
SB Dunks run narrower through the midfoot than the AJ1. Same labeled size will feel tighter across the middle of the foot.
