Both are Nike models, but lasts differ. Air Max 90 is labeled True to Size (True to size; half up if wide feet). Air Force 1 '07 is Runs Big (Size down half a size (TTS if wide feet)).
Air Max 90 is a strong TTS Nike reference — owner datasets align it with Jordan 1 and Dunk length, about a half size shorter feel than roomy AF1. Start with your usual Nike size; wide feet commonly half up for mudguard volume.
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.
