Sole slip is the basic functional requirement of high-protective shoes, but many people still suffer from injuries caused by slipping or falling high-heeled shoes every year. Although there are major differences in the anti-slip and anti-slip standards for soles due to different venues, different uses, different jobs, or different types of shoes, as a sole or footwear manufacturer, the choice of sole material and sole design At the same time, it should still pay enough attention to its anti-slip function. Generally, the outer sole material of high-top labor insurance shoes should have oil resistance, slip resistance, wear resistance, pressure resistance, water resistance, good elasticity, heat resistance, impact resistance, easy to fit the foot shape, not easy to change after setting, heat preservation, easy to absorb moisture, etc. At the same time, it is necessary to cooperate with the midsole. When walking and changing feet, there are brakes that do not cause slipping and easy parking.
There are many factors affecting the anti-slip of high-top labor insurance shoes, such as sole material (high-top labor insurance shoes sole material including rubber, plastic, rubber and plastic materials, PU/PU, PU/TPU, PU/RUBBER, etc.). Ground hardness, dry Humidity, smoothness, sole pattern, structure, etc. The anti-slip effect on dry ground is often referred to as dry slip. The anti-slip effect in the presence of water on the ground is called wet slip. In some special working or living environments, what exists on the ground may not be just ordinary water, but often oil, even oil and water. Therefore, there are oil-type anti-slip and oil-added anti-slip. For different environments, shoes have different shoe and sole designs for the anti-slip function.
The rough and uneven height of the bottom of the high-protective shoes can effectively increase the actual contact area, thereby increasing the friction and improving the anti-slip effect. The structure, thickness and depth of the different shadings are different from the actual contact area with the ground. The fine lines are easy to wear when supporting the human body, resulting in a rapid weakening of the anti-slip effect; too thick shading, walking on the general road, the deformation is reduced and the anti-slip effect is not good. Therefore, the design of the high-protective shoes's soles is more important in the wet interface. In the wet contact environment, the drainage pattern of the drainage directly affects the slip-proof effect of the sole. When there is water between the sole and the contact surface, the texture of the sole cannot effectively remove the water to the groove of the shading and the sides of the sole, and water will exist between the sole and the ground, and the thin water layer plays a lubricating role. Greatly reduces the friction between the sole and the ground, causing slippage. Therefore, the design of the upper shoe line of high-top labor insurance shoes should consider both the dry contact surface and the wet contact surface.
