The outsole, which is in direct contact with the ground, is usually made of synthetic rubber material to increase comfort, while the heels are relatively low, light and anti-slip, and the bottom surfaces are provided with grooves for preventing slipping down. Some women's boots have a middle sole between the inner sole and the outer sole, and the middle sole is also made of nylon synthetic material and has shock absorbing buffering microporous structure.
As the times change, the boots are made in a plurality of kinds, and female friends can select according to the love. However, because the boots for women have the boot leg, once the boots are wet, the boots for women are difficult to air and dry, and the boot vamp is generally made of PU or cloth, so that the waterproof effect is poor, rainwater easily permeates into the boots when the boots are worn in rainy days, the wearing experience is affected, and the boot vamp is easy to absorb water, so that the boots for women swell and the service life of the boots for women is shortened.
In order to improve the surface waterproof property of the woman's boots, patent publication No. CN112263041A discloses a waterproof woman's boot and a preparation process thereof, the boot surface is treated by a waterproof finishing agent, and the waterproof finishing agent comprises melamine, formaldehyde, polymethyl methacrylate, dimethylaniline, ammonium persulfate, p-nitrophenylacetate, dimethylaminopyridine, eleostearic acid anhydride, an emulsifier and fatty acid alkanolamide.
However, the applicant has found that the technical solution of the above patent has the following drawbacks: the components such as formaldehyde, dimethylaniline and the like are harmful to the health of human bodies, and are easily oxidized in the air or in the sunlight, so that the aging phenomenon of the boot vamp is accelerated, and the service life of the boots for women is shortened.
