height reinforcement titanium ion arch correction insoles: insoles align the spine, feet and pelvis while providing excellent arch support. Improves arch and leg shape: the arch support of Sugola insoles improves the shape of the legs, relieves problems caused by flat arches and repositions the ligaments of the legs and restores bone growth. insoles use special fibres to improve blood circulation, reduce inflammation and relieve fatigue, which contributes to foot health and general well-being. insoles can adjust the cut size. Ion technology: insoles use ion technology to create negative ions that neutralise the positive ions in the environment. Sugola insoles create a balanced environment that reduces stress and promotes well-being. Promotes bone growth: Sugola insoles promote bone growth through the interaction of titanium ions and negative ions. This increases the width and pores of the bone trabeculae, stimulates the formation of new bone cells and supports the growth and extension of legs, arms and spine.
