Importers of Footwear Parts, Removable Insoles, Heel Cushions, Gaiters, Leggings, and Similar Articles (NESOI) paid $2.6M in duties in August 2026, an average duty rate of 15.68% — duty actually collected as a share of the imports that cleared customs, not the published tariff schedule.

Last updated: August 2026 dataChina and Vietnam dominate supply of this broad residual heading, which consolidates an unusually diverse set of products: removable insoles and heel cushions, wooden footwear parts, leg warmers (with dedicated lines for manmade fiber, cotton, and wool blends), leather and rubber/plastic footwear parts, and a general NESOI catch-all. South Korea and Taiwan are also notable suppliers, particularly for technical insole and cushioning components used in athletic and orthopedic footwear. The presence of leg warmers within a footwear-parts heading is a classification nuance — they land here because they are worn on the lower leg in conjunction with footwear, not because they are structural shoe components.

Heading 6406.90 explicitly covers gaiters, leggings, and similar articles worn over the lower leg in connection with footwear, pulling them out of the apparel chapters. Leg warmers that cover only the leg without a foot portion classify here; items that also cover the foot may shift to hosiery in Chapter 61. The distinction matters because Chapter 64 and Chapter 61 carry different duty rates and textile quota/visa requirements.
A removable insole is designed to be taken out of the shoe by the consumer — for replacement, orthotic use, or comfort adjustment — and is sold separately or as a clearly separable accessory. An insole that is permanently bonded or stitched into the shoe during manufacture is a component of the finished footwear and does not classify separately under 6406.90. When insoles are imported loose in bulk for aftermarket sale, they clearly belong here; when imported as part of a shoe kit, the classification of the complete article governs.
