[Product] Insoles for shock absorption, insoles to reduce fatigue/antibacterial/flat feet/powerful deodorization/memory foam/plantar fasciitis correction, size adjustable, 3D arch support based on human engineering, arch support, soft cushion, suitable for sports, running, and mountain climbing (24~27.5CM) Purchase Date: 2025/1 [High-Quality Materials] The insoles are made of soft and comfortable high-quality memory cushion foam, protecting the ankles and providing excellent wear resistance and a superior experience. The top is made of high-grade velvet material, with a delicate, smooth, and soft texture, providing the most comfortable experience. [Excellent Breathability] The design of the ventilation holes effectively wicks away moisture, allows air circulation, reduces odor, and keeps your feet breathable and dry all day long. Quick-drying, no need to worry about sweating or moisture, keeping your feet away from bacteria and odors. [Deodorization] Made of ultra-lightweight and elastic sponge material, with numerous small pores invisible to the naked eye, used for ventilation and perspiration to achieve a deodorizing effect. Makes you feel light when walking, running, or climbing!! Easily cut with scissors you have at home, and you can fine-tune the size to fit your shoes. M: 24-27.5cm [Arch Support] The arch part of commercially available sports insoles also has drawbacks; the material is hard and protrudes too much, so walking for a long time causes pain and fatigue in the inner longitudinal arch of the foot. Our insoles adopt a hidden protrusion design for the arch part, the same height as the heel. While walking, the arch part of the insole receives pressure and fits the sole of the foot, providing firm support. When not walking, the arch part of the insole, of course, does not put pressure on the foot. [Perfect for All Occasions] Lightweight, breathable, and soft, this insole provides the best support, and complete relief for sports, work, and leisure, keeping you comfortable all day long. The insoles are designed for various shoes such as tennis shoes, basketball shoes, running shoes, casual shoes, and leather shoes, and are suitable for all sports needs, running, basketball, soccer, mountain climbing, camping, etc.
