The upper is one of the main components of a shoe. For smooth shoes, it is important to check if they are soft and full, and if there is any looseness when pressing the shoe upper with your hand. A good shoe upper should be full and soft, with a comfortable touch, uniform and consistent luster, and no looseness. For the upper of suede shoes, attention should be paid to checking whether the fuzz is short and uniform, and the color tone should also be consistent. The shoe lining is a part of the shoe upper, used to strengthen the upper, prevent the upper from extending and deforming, and improve the foot feel. So, good shoe lining materials (such as genuine leather shoe lining) should have good touch, breathability, and moisture wicking properties, and are not easy to fade. In sewing, there should be no wrinkles or fat edges inside the shoes.

When the shoes are dirty, they can be gently brushed with detergent dipped in clean water, then rinsed with clean water, placed in a well ventilated and cool place to air dry, avoiding direct sunlight. Do not use heating or open flames for drying to avoid aging, peeling, fading, and severe deformation. Excessive direct sunlight, hot air from hair dryers, and improper care methods can all reduce the lifespan of shoes; When washing, do not soak for a long time, and generally do not soak for more than 20 minutes. Genuine leather shoes should not be soaked in water.
