Thank you for viewing! 【Anonymous Delivery】【Price negotiations are welcome!✨】 ⭐ For those troubled by foot discomfort or chronic poor posture, as well as those who want to prevent future strain on their bodies. This insole provides a strong foundation to support your healthy daily life and walking. It "flexibly absorbs" impact and "gently pushes back" during walking, significantly reducing the burden on joints and muscles, achieving "fatigue-free insoles." ⭐ This arch support insole, with its rare and sophisticated half-structure, is thin and slim, yet firmly supports the arch of the foot, thoroughly overcoming the weaknesses of conventional products. Above all, you can use it by layering it on top of your original insoles, eliminating the need for troublesome removal. It fits snugly, so it doesn't slip, and its compact and flexible design allows it to fit easily into a bag or pocket, supporting comfortable feet anytime, anywhere. ⭐ Many foot problems stem from the "collapse of the arch," or flat feet. Flat feet not only make walking tiring but also cause a chain reaction of discomfort throughout the body. When the arch collapses, the shock absorption function decreases, causing the ankles to tilt inward (pronation), increasing the burden on the knee joints. Furthermore, it leads to pelvic tilt, ultimately affecting the posture of the lower back and neck, and is deeply involved in the causes of knee pain, lower back pain, and stiff shoulders. TARKINS flat foot insoles address this root cause. They are arch support insoles with a reinforced design using high-hardness, high-support materials for the arch. Rather than simply "raising" the arch, they firmly support the arch with scientifically calculated optimal curvature and hardness. By improving the pressure distribution on the soles of the feet and guiding them to a natural alignment (bone arrangement), they support posture correction. They cut off the chain of load that runs from the feet → knees → lower back → neck, effectively alleviating pain throughout the body caused by the structure. <Easy Installation> After confirming the left and right, align the heel of the insole with the heel of the shoe and insert it. (If there are removable original insoles, you can layer it on top.) After wearing, it fits your feet, and you can feel stable comfort as the insole does not shift forward or backward. <How to Choose Your Size> Please choose the size that matches your foot length (cm). ▲Note: There is an overlap in size ranges. We especially recommend size M for those with 24.5cm feet and size L for those with 26.5cm feet.
