Thank you for viewing! Gentle fit for your feet with a 3-layer structure! High-cushion EVA, with low-rebound urethane in the forefoot and high-rebound urethane in the heel. Two different types of urethane support comfortable walking. A soft and comfortable insole using two types of urethane: low-rebound and high-rebound. The low-rebound urethane fits like a wrap, conforming to the shape of your foot. The high-rebound urethane utilizes its resilience for a spring effect, supporting movement while walking. The fabric uses specially processed polyester to prevent slipping inside the shoe, and is treated with "Biosil," an antibacterial agent developed by Dow Corning. The sole material is lightweight and soft EVA with ventilation holes to reduce stuffiness. What is low-rebound urethane? It has low resilience, slowly distributing pressure and absorbing impact. What is high-rebound urethane? It has high resilience and excellent restorative force, pushing back when pressure is applied. [Precautions for Use] ・The insole size is standard, but the width may not fit depending on the shoe. ・The inside of the shoe may become narrower when the insole is inserted. ・If you feel any abnormality in your feet, discontinue use immediately. ・Cannot be washed.
