That is, the sole is relatively high, so it can't really increase. Invisible inner heightening shoes have six characteristics: 1. Invisible heightening shoes have the same appearance as ordinary leather shoes, and the built-in heightening layer can invisibly increase the human body by 5- 10 cm. 2, the height-increasing shoes are light and breathable, and the inner height-increasing layer is light and elastic, which helps to reduce vibration and protect the human brain and other organs; There is an air circulation system in the shoes, which can play the role of ventilation in the shoes, and can also prevent moisture, sweat and deodorization. 3. Height-increasing shoes have complete styles and beautiful appearance. There are a series of heightening shoes for men and women, including singles, cotton and sandals. The height increases by series, including ordinary high-top shoes (4-6cm), medium-high-top shoes (6-7cm) and ultra-high-top shoes (7.5- 10cm). 4. The design of height-increasing shoes is scientific and the curve design is reasonable. According to the skeleton structure and mechanical stress principle of human foot, a high floor is added in the shoe, which is consistent with the sole of the foot, and there is no discomfort of ordinary high heels. 5. Multifunctional height-increasing shoes can correct the figure, improve the habit of hunchback and bending, and make people stand up straight and confident. Especially suitable for people with flat feet (adding a high floor is equivalent to adding an arch). 6, high-quality shoes, all leather shoes are made of small and medium-sized cowhide.
