6404.11.51.90 - Other

This classification pertains to sports footwear that does not fit into more specific descriptions within the broader category of sports footwear with outer soles of rubber or plastics. The defining characteristic of this subcategory is that its upper is constructed from vegetable fibers. Furthermore, the outer sole of these shoes must contain textile materials that constitute the largest surface area in contact with the ground. It is crucial to note that the textile components of the outer sole should not be considered under the provisions of Additional U.S. Note 5 to Chapter 64.

This "Other" category serves as a residual classification for sports footwear made with vegetable fiber uppers and specific textile-based outer soles, distinguishing it from footwear with different upper materials or outer sole constructions. It specifically captures items that do not fall under the "For men" or "For women" subcategories at the same hierarchical level, implying a unisex or gender-neutral design or where gender-specific design is not a primary classification factor for these particular goods.

As this is a leaf node, there are no further subcategories. Therefore, classification within 6404.11.51.90 hinges on the precise material composition of the upper (vegetable fibers) and the predominant textile material in the outer sole's ground-contacting surface, excluding specific instances addressed by Additional U.S. Note 5. Examples could include certain types of training shoes or casual athletic footwear where the primary upper material is derived from natural plant fibers, and the dominant component of the outsole tread is textile-based.
