RT250004 is a PU-based sport-functional insole designed for brands and distributors that require a hybrid solution combining cushioning, orthotic support and enhanced foot stability. This model integrates a heel cup structure, PU cushioning layers and corrective midfoot geometry, making it suitable for sport-lifestyle footwear, work sneakers and supportive everyday shoes.

The top layer features a smooth, durable fabric with printed motion graphics, enhancing grip and reducing friction within the shoe. Beneath this textile lies a contoured PU platform engineered to deliver a balance of comfort, resilience and guided foot alignment. PU is well-known for maintaining shape under repeated compression, ensuring long-lasting support in high-usage environments.

A key feature of this insole is the molded heel cup, which stabilizes the rearfoot by reducing lateral movement during walking or light athletic activity. This structure helps improve overall foot alignment and reduces unwanted pronation, contributing to a smoother and more controlled gait.

The arch zone incorporates a built-in corrective contour, offering moderate support suitable for users who require gentle alignment assistance without the rigidity of a medical orthotic. This makes RT250004 an attractive option for sport-inspired product lines where comfort and support need to coexist.
