The choice of material directly impacts traction, weight, and durability. TPU (Thermoplastic Polyurethane) is the industry standard for its excellent abrasion resistance and flexibility. For professional-grade lightweight performance, Pebax® is preferred due to its superior energy return and lower density. For budget-friendly or turf-specific outsoles, RB (Rubber) provides the necessary grip and shock absorption. Ensure the supplier uses virgin materials rather than recycled scraps to prevent premature cracking under high stress.
