For footwear brands, the prize is not simply a lighter upper; it is a shorter, more integrated product-development and manufacturing model.
New Balance has highlighted warp knitting as a strategically important technology for performance footwear, arguing that it can compress product development, reduce material waste and integrate multiple functional zones into a single textile upper. The message, delivered by Senior Textile and Materials Engineer Vishnu Prakash Muthusamy at KARL MAYER’s Textile Innovation Center in Obertshausen, points to a growing role for warp-knitted constructions in athletic shoes.
From component assembly to engineered uppers
Modern sports shoes can contain up to 30 components, including uppers, overlays, reinforcements and appliqués. Conventionally, these are cut, bonded and assembled through multiple operations—adding weight, complexity, material losses and development time. Warp knitting offers an alternative: structural support, breathability, stretch control and aesthetic effects can be incorporated directly into the fabric rather than added as separate parts.
This approach, often described as zonal engineering, uses controlled stitch density and Jacquard-guided yarn placement to create ventilation zones, midfoot support, heel stability, tear-resistant lace areas and visual details within the same textile construction. It can reduce dependence on printing, laminating and secondary applications while improving dimensional stability and strength-to-weight performance.
Development speed becomes a sourcing advantage
The commercial case is equally significant. New Balance said design changes can be transferred digitally to compatible warp-knitting machines without new pattern discs or tooling. In the development model described, a design may need to shift within seven days, new material must be assessed within 14 days, and the finished shoe must be produced within 45 days.
For footwear-material suppliers, this moves the relationship beyond fabric supply. Brands increasingly need partners that can translate biomechanical, aesthetic and sustainability requirements into reproducible textile structures at development speed.
A measurable material-efficiency case
In one cited development project, New Balance increased yield from four to five shoe pairs per yard of fabric—an effective 25% increase in pairs produced from the same fabric length. The company reported material-cost savings of up to 28%, with virtually no waste, supported by zonal placement accuracy of approximately ±2 mm. These are company-presented project results rather than independently audited industry benchmarks.
Near-net-shape production could also support durability and circularity by reducing component count and enabling more mono-material constructions using recycled or bio-based yarns.
The next opportunity lies in 3D, biomechanically informed warp-knitted structures. Mills and machinery users that can combine design engineering, digital patterning and footwear testing may become more valuable partners in the race for lighter, faster-developed and lower-waste athletic shoes.
