RT250415 is a lightweight EVA comfort insole designed with a full-surface ventilation mesh structure, providing excellent breathability and enhanced comfort for everyday wear. The insole combines soft EVA cushioning with a perforated design that efficiently promotes airflow, helping to reduce moisture buildup and keep feet dry throughout the day.

The top layer of the insole uses a breathable mesh fabric that improves moisture absorption and enhances step-in softness. This layer sits over a molded EVA base engineered for long-lasting resilience. EVA is known for its combination of cushioning, flexibility, and lightweight properties—making this insole suitable for users who prioritize comfort without the need for rigid arch support.

The yellow EVA bottom incorporates a dense matrix of ventilation holes, allowing air to circulate with each step. This structure not only improves cooling performance but also reduces overall weight, making RT250415 an ideal component for casual shoes, work shoes, summer footwear, sports lifestyle shoes, and daily-use sneakers. The perforated base also improves shock absorption by allowing the material to compress and rebound more efficiently under repeated pressure.
