Both are Nike models, but lasts differ. Lunar Force 1 is labeled True to Size (True to size (do not copy AF1 half-down); half up if wide feet or thick winter socks). Air Force 1 '07 is Runs Big (Size down half a size (TTS if wide feet)).
Does the Nike Lunar Force 1 (duckboot) run big or small? Retailer fit tags and wearer reviews commonly land on true to size — unlike summer Air Force 1 ’07, where many size down half. Do not copy AF1 half-down advice onto Lunar Force 1. Wide feet or thick winter socks may need half up. Confidence is medium: TTS is the modal report, but collar bulk varies by foot shape.
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.
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.

| Break-in | Leather/upper softens; insulation pack-out is limited vs summer AF1 | Leather softens with wear |
