Generally, shoes bought in the market are not suitable for high-type insoles, and manufacturers need to make special shoe molds.

The heightening principle of the concealed inner heightening shoes is to make the inner heightening pad of special pressure-resistant and breathable materials and put it in the specially designed shoes to achieve the heightening effect. Similar to women's high-heeled shoes, but the design structure is much more comfortable than women's high-heeled shoes, and there is no discomfort after wearing them. The appearance of the concealed inner heightening shoes is the same as that of ordinary high-grade leather shoes, which not only makes people not see the secret of heightening, but also makes people feel comfortable.
