Both are Nike models, but lasts differ. Air Force 1 '07 is labeled Runs Big (Size down half a size (TTS if wide feet)). Dunk Low is True to Size (True to size; half up if wide).
Nike’s own AF1 guide says they generally run big from the roomy toebox and recommends half a size down from your usual Nike size. Wide feet can stay TTS. Leather loosens further with break-in.
Dunk Low is a common TTS Nike reference — closer and more tapered than Air Force 1. Average feet take their usual size; wide feet may prefer half up. Do not copy an AF1 size-down into Dunks without checking.
Use the table below as a starting point from fit offsets — then confirm with try-on or returns. Width can matter more than length between these two.
| Air Force 1 '07 | Dunk Low | |
|---|---|---|
| Verdict | Runs Big | True to Size |
| Advice | Size down half a size (TTS if wide feet) | True to size; half up if wide |
| Width | Roomy boxy toebox | More tapered than AF1 — can feel snug in toebox |
| Break-in | Leather softens with wear | Minimal |
| Fit offset | -0.5 | +0 |
| Confidence | high | high |
If the left model fits at the listed size, start here in the right model (chart + fit offsets).
| If Air Force 1 '07 fits | Try Dunk Low | Note |
|---|---|---|
| US 7 | US 7.5 | offset +0.5 |
| US 7.5 | US 8 | offset +0.5 |
| US 8 | US 8.5 | offset +0.5 |
| US 8.5 | US 9 | offset +0.5 |
| US 9 | US 9.5 | offset +0.5 |
| US 9.5 | US 10 | offset +0.5 |
| US 10 | US 10.5 | offset +0.5 |
| US 10.5 | US 11 | offset +0.5 |
| US 11 | US 11.5 | offset +0.5 |
| US 12 | US 12.5 | offset +0.5 |
The size-bridge table is all offset +0.5: if AF1 '07 fits at US 10, Dunk Low starts at 10.5. US 7 → 7.5 through US 12 → 12.5. The wear-box and the reverse (−0.5 back to AF1) say the same thing. Snapshot offsets: AF1 −0.5 (runs big, half down unless wide) versus Dunk +0 (TTS; half up if wide). The +0.5 is undoing AF1’s length-down so you land on Dunk TTS — it is not “Dunk runs small.”
If your AF1 already fits at a half-down from your usual Nike size, this bridge puts you back on that usual size in Dunk. Example: usual Nike 10, AF1 worn at 9.5 → table from 9.5 starts Dunk at 10. Feeding the labeled AF1 10 (if you did not size down) into Dunk 10.5 is for people whose AF1 10 actually fits — often wide feet who stayed TTS in AF1. Do not stack “I sized down in AF1” and then +0.5 from the original 10.
Width still differs after the number matches. AF1 is a roomy boxy toebox; Dunk is more tapered and can feel snug. Wide feet who stayed TTS in AF1 may still want Dunk’s “half up if wide” on top of this length bridge — that is a width call, not a second length offset from AF1. Start at the bridged number, then decide width separately.
