Universal insoles providing comfort and freshness to your feet all day long. Made from two layers of latex with different densities, enriched with granular charcoal that absorbs sweat and unpleasant odors. The breathable material lining guarantees comfort and additional ventilation. Designed for people who walk on hard surfaces, experience excessive foot sweating, and for shoes with thin soles (absorbing micro-shocks and static and dynamic pressures). Suitable for all types of footwear. MATERIAL: top layer – material with granular charcoal, bottom layer – latex of varying densities. INSTRUCTIONS: Place the insoles in the shoes with the fabric side towards the foot. Remove and dry at room temperature if they become moist. For proper hygiene, replace insoles every 4-6 weeks.
