The bottom layer features a contrasting red-and-grey foam structure with molded traction patterns. This layer improves stability inside the shoe, preventing slippage and helping the insole maintain its shape over time. The textured pattern also enhances flexibility, allowing the insole to move naturally with the foot while providing mild support across the arch and heel zones.
The lightweight, compressible nature of the foam ensures compatibility with a wide range of footwear categories without increasing internal shoe volume. RT250518 works especially well in fashion sneakers, canvas shoes, slip-ons, work-casual shoes and children's footwear.
OEM/ODM customization options include foam density adjustments, thickness variations, top cover textile changes, color customization, branding application and multiple packaging formats such as blister cards, polybags or private-label boxes.
With its simple yet effective cushioning design, RT250518 provides a versatile and cost-efficient comfort insole solution for B2B partners seeking reliable, everyday comfort products to enrich their footwear accessory assortments.
