The selection of shoe materials is not only for appearance, but to a large extent, it is also considered from the aspects of the hygiene performance of the shoes. The comfort of the shoe is related to the microclimate in the shoe formed by it. The natural grain leather and cotton textiles in the upper material have excellent hygienic properties. Because the material has good air permeability, water vapor permeability, and moisture absorption, there are prerequisites for not stuffing your feet or covering your feet. At this stage, the various synthetic leathers and artificial leathers developed in our country are far inferior to natural leather in terms of sanitary performance. Therefore, when designing, select suitable materials according to the style, wearing conditions and environment to improve the wearing comfort of shoes. Although heavy-modified top leather and two-layer leather are leather shoe materials, their surface is covered with coatings, and the pores of natural leather are blocked, so their breathability and water vapor permeability are greatly compromised. The upper textile materials should pay attention to the selection of materials with good hygienic performance and comfort, such as breathable, moisture-absorbing, light, soft, sterile, deodorant and other materials. Excellent materials for shoe uppers must be used in conjunction with linings, insoles, inner caps, adhesives and other materials to give full play to their superior performance. Rico, the shoe material has the closest contact with the foot, and accepts steam and sweat from the feet. If Rico itself does not have the function of breathability and moisture absorption, the hygienic performance of the fabric will not be exerted. Good quality shoe insole materials should absorb moisture, breathe, have good dimensional stability, flexural resistance, etc., to meet the requirements of use, and will also give the feet a comfortable bottom environment.
The performance of the sole material greatly affects the comfort during wearing. Choose the shoes according to the occasion and purpose of use. For general shoes, the soles used in the design should be light in weight and moderate in hardness. If the hardness is too low, there is no rigidity, and the feet are easy to strain; if the hardness is too high, the feet cannot be bent along with the feet when walking. Both situations can easily cause foot fatigue.
