Hello, heightening the insole is mainly through internal heightening, which makes women's height increase and lean forward to form a typical S-shape, which is conducive to maintaining women's perfect figure. Because the center of gravity moves forward, the body naturally turns back to maintain balance. Wearing high insoles will change the leg shape, deform the muscles and change the figure, which is the same as wearing high heels. The overall curve will be perfect, but it may affect the height, which is not conducive to increase.
