Sports footwear under 640411 is designed for athletic activity — typically featuring reinforced toe boxes, cushioned midsoles, or other performance construction. Canvas slip-ons, fashion sneakers, or casual shoes that share a textile upper and rubber sole but lack athletic-performance design features generally fall under 640419. Marketing alone does not determine classification; construction and design intent matter.

Classification depends on the material of the outermost surface of the sole — the part that contacts the ground. If rubber or plastics form the ground-contact surface, the article falls under 640411 or 640419. If leather or composition leather is the ground-contact surface, 640420 applies. A thin rubber layer on the bottom typically directs classification to the rubber-sole subheadings.
