1. Material identification: According to the materials of slippers on the market, there are no more than sheepskin, cowhide, synthetic leather, plastic, rubber, gauze cloth, etc. Leather slippers can absorb sweat, heat insulation and comfort, and the time of wearing will change. Slippers with longer synthetic leather are worse than leather slippers; plastic slippers are light and cheap, but they do not absorb sweat and have poor air permeability.
2. Appearance quality inspection: For slippers of any material, the thickness, fineness, and color depth of the front and rear sides of the same pair must be consistent, and there should be no cracks, shells, glue stains, etc. In addition, the upper of the slippers is best not high or low, and it is the standard that the ankle bone is not stuck.
3. Workmanship inspection: Whether the needle thread of the upper surface and the upper thread of the upper part are neat, the upper part must be firm.
4. The size is right: Do not buy shoes that are too tight, especially girls with fat feet should buy shoes one size larger, so as not to overfill the shoes and give people a more bloated feeling. If it is a pointed shoe, there should be a margin of 1 cm between the big toe and the toe.
