Design and Integration of Functional Protective Gear in Tennis and Badminton Footwear

Abstract

Research summary supplied by the authors

Tennis and badminton footwear undergo severe localized stresses at the toe-box, lateral forefoot and flex regions due to frequent dragging, abrupt multidirectional movements, and repeated highintensity impacts on varied court surfaces. These factors lead to premature material failure, especially in knit, mesh, and synthetic leather uppers. Players typically replace 2–3 pairs of shoes per quarter, incurring high personal costs and contributing significantly to non-biodegradable footwear waste. Currently, no rapid, in-situ repair technology or stressdissipating toe-box protection system exists, resulting in early upper rupture and reduced performance lifespan. Addressing this critical gap requires functional surface engineering and protective design strategies that extend durability without compromising comfort, flexibility, or playability. The present project proposes a dual-technology approach: the design of equally stress-dissipating toe-box protectors using graded overlays, lattice geometries, sacrificial microrib patterns, and auxetic load-spreading structures. These coatings will combine abrasion resistance, high elasticity, strong adhesion, water/dirt repellency, and environmental stability using polymeric dispersions, nanocomposites, and bio-based systems. The research will be executed through a structured methodology consisting of wear pattern mapping (pressure mapping, motion capture, and finite element analysis), formulation and optimization of coatings, laboratory characterization using ASTM/ISO standards, prototype development, and real-time athlete trials on hard, clay, grass, and wooden/PVC courts. Laboratory evaluation includes abrasion resistance, flexibility and tensile behavior, adhesion and hydrophobicity. The optimized coatings and protector designs will be integrated into prototype tennis and badminton shoes, followed by field validation with athletes to assess durability, comfort retention, repair efficacy, and material performance under actual playing conditions. The anticipated outcomes include functional, readyto-use coatings for factory and on-field repair, stressdissipating toe-box protector designs with CAD/CAM support, coated and validated prototype footwear.
