Nike Sues Skechers and New Balance Over Flyknit-like Upper Tech

Nike has filed a patent infringement lawsuit against Skechers and New Balance, alleging that the two rivals used a patented sneaker upper technology to manufacture their products. The claim focuses on Nike Flyknit, a technology the company says enables high-performance shoes with minimal material usage and reduced waste, delivering both lightness and strength in the upper portion of the shoe. The filing asserts that Skechers Arch Fit, Glide Step, and Ultra Flex 3 running models, as well as New Balance Fresh Foam and FuelCell lines, incorporate the same claimed technology. In response to prior litigation, Nike notes that it has previously pursued patent infringement actions against Skechers. According to industry reporting, Nike has solidified its position as a leading brand in the athletic footwear market, a status highlighted by market analytics from Statista in August. Separate market coverage has pointed to Nike’s prominence in global footwear brand rankings, emphasizing its wide consumer recognition and demand. The broader context for these developments includes ongoing competition among major athletic brands to innovate with materials, performance, and design, while balancing manufacturing efficiency and environmental considerations. Analysts observe that Flyknit and similar upper technologies have shaped product differentiation and consumer expectations across the running category. The lawsuit underscores how intellectual property rights influence product strategy, supplier choices, and the pace of design evolution in the sportswear sector. Industry observers note that patent protection remains a critical factor as brands scale global production, respond to consumer demand, and explore new sustainable manufacturing approaches. The case adds to a history of patent disputes within the athletic footwear space, where several companies have pursued or defended claims over advanced knit constructions and other proprietary methods. Nike’s position in the market continues to be closely watched by retailers and fans, who often weigh performance attributes against price and availability. In the broader landscape, brands are continually balancing innovation with supply chain realities, aiming to deliver high-performance gear that resonates with athletes and casual wearers alike. The ongoing legal actions illustrate how closely technology, design, and brand identity are interwoven in today’s competitive sneaker market, where small improvements in upper construction can translate into meaningful differences in fit, feel, and durability. Observers caution that outcomes in patent litigation can influence future product development timelines, licensing opportunities, and strategic partnerships across the industry. The dialogue around Flyknit and similar technologies also intersects with sustainability narratives, as manufacturers seek to reduce material waste and enhance recyclability while maintaining strength and performance. Overall, the sector continues to experience rapid change driven by new materials science, advanced manufacturing techniques, and a competitive drive to secure consumer loyalty through standout design and performance credentials.
