RT250416 is a comfort-focused EVA insole engineered with a ventilated structure and targeted cushioning zones, offering enhanced comfort for daily walking, light activity, and long hours of standing. The combination of a breathable mesh top fabric with a fully perforated EVA mid-layer enables efficient airflow, helping reduce heat accumulation and moisture throughout the day.

A distinctive feature of this model is the integrated metatarsal pad positioned in the forefoot area. This pad provides localized cushioning that helps redistribute pressure across the metatarsal region, making the insole suitable for users who experience forefoot fatigue during extended use. Additionally, the heel area incorporates a soft shock-absorbing insert to reduce impact forces and improve overall step comfort.

The red EVA base features a honeycomb-style ventilation system, contributing to both lightweight comfort and flexibility. This structure allows the insole to compress and rebound effectively during movement, maintaining durability even under frequent wear. The ventilated design also enhances comfort in warm climates or in enclosed footwear where airflow is limited.
