Shock Absorption: The material is made of high-quality PVC that absorbs shock and reduces pressure on the feet with every step. It is suitable for high-intensity exercises and helps reduce exercise-related fatigue, such as shin splints, runner's knee, and plantar fasciitis. Breathable and Odorless: Keeps your feet breathable and dry, reducing odors. Height: The insole is a single layer, 3cm thick. Sports, Work, and Leisure: The insoles are ultra-soft and gentle, ideal for improving performance and reducing pain during physical activity. Good results can reduce the effects on joints and muscles. The U-shaped heel helps stabilize and support the foot and positions the heel to naturally absorb shock during high-impact activities and long-distance movements. The insoles are ideal for athletic shoes, casual shoes, and work shoes. If you need to walk or stand for a long time, you can't miss it.
