Bottom Line
Wrong size is the most expensive rep mistake — return shipping costs more than the price difference between batches. I measured insoles across five models and six batches to build this reference. Most Nike reps run TTS with model-specific exceptions documented here.

About This Guide
Default: TTS for most Nike reps. Half up on Air Max 97 (long and narrow), Shox (tight toe box), and SB Dunks (padded tongue reduces volume). Half down rarely needed. Measure your insole from a shoe that fits and compare against the data on this page.
