Nike's checked AF1 listing recommends considering half a size down. That is AF1 advice; it does not establish a Lunar Force order size. The Lunar listing's review summary is labelled AI-generated. We do not turn its reports of fit into a universal TTS rule or a fixed adjustment for winter socks.
Use the actual socks you intend to wear when trying the duckboot. Check toe clearance while standing, heel movement while walking, and pressure around the instep and ankle. Compare the full size system on your existing pair with the seller's chart; matching numbers do not prove matching internal space.
Insulation, upper construction and lacing are reasons to inspect the actual fit, not measurements of how much to add to a label. If width is the problem, investigate width and shape before increasing length. Do not rely on a promised break-in change to fix cramped toes.
The checked Lunar product is described as water-repellent; this is not a guarantee for every depth, duration or condition. It is not intended as personal protective equipment. Verify the exact product specification for your use.
