Scientific Correction Principle: Researched and designed by an MD in Italy, multidimensional double triangular correction, effectively blocks the ankle, improving the false force in the foot to balance the foot in the process of walking and strengthens the stability of the foot. Arch and ankle support: Designed according to biomechanics and ergonomics, it fits the foot perfectly, effectively fixes the heel of the foot, prevents slippage to the left or right and the appearance of flat feet, supports arches and ankles, and allows muscles to exercise well. High-top shoes: Velcro straps allow you to adjust the strap length to fit different foot widths, strengthen shoe stability, maintain proper posture, and prevent and correct heel tilt in children. Non-slip sole and hard heel: With a flat layer of artificial physiology, properly distribute the load of the musculoskeletal system, ensure that the child’s foot is in the correct position, strengthen the gripping sensation, improve the baby’s balance ability when standing and protect the baby from easy falls, relieve pressure on the heel, make the feet evenly stressed and improve posture when walking.
