RT250007 is a PU-based sport insole designed for footwear brands and distributors seeking a lightweight, highly breathable and soft-elastic cushioning solution for athletic and lifestyle footwear. Its construction focuses on ventilation, responsiveness and all-day comfort, making it suitable for running shoes, training sneakers, walking footwear and multipurpose sport-casual models.

The top surface features a soft, abrasion-resistant fabric that enhances step comfort while maintaining low friction inside the shoe. It provides a smooth experience during prolonged wear and helps manage moisture by allowing airflow to circulate through the insole structure.

The defining feature of RT250007 is its full-length perforated PU body, engineered with a grid of ventilation channels that promote continuous air exchange. These perforations significantly improve breathability, helping regulate in-shoe temperature during sport activities or extended walking periods. For consumers, this translates into reduced heat accumulation and a fresher wearing experience.

The PU foam itself is formulated for soft elastic rebound, providing a cushioned yet responsive feel underfoot. It adapts to pressure changes during movement, distributing impact forces across the heel, midfoot and forefoot while maintaining consistent support. This material choice enhances comfort without sacrificing durability, making the insole suitable for daily high-frequency use.
