Technical Field
The invention relates to the field of elastic soles, in particular to a preparation process of a wear-resistant and anti-slip golf sole.
Background
Golf is not a very intense sport and the playing rhythm is not very jerky, and although the feet do not bear very great impacts at all times, a distance of about six kilometers is typically required to complete an 18 hole. In this process, the whole body weight is placed on both feet, so that a comfortable pair of shoes is selected, and the method is a good method for protecting both feet, neither for amateurs nor professionals, from suffering from bitter taste, nor from injury to ankles.
The shape, material, structure and fittings of the golf sole are different from those of the common shoes. In particular, the sole nail ensures that the player stands stably, has a feeling of stepping on the ground, and helps to walk and slip on uneven road surfaces. The soles of the general golf shoes are provided with a plurality of short nails made of rubber, so that the soles can be prevented from slipping, grass can be walked more stably, the body can be kept balanced during the swing, meanwhile, the turf is protected, and the golf shoes are more specialized in appearance.
The golf shoe sole is required to have anti-slip, waterproof and lightweight effects to more stably walk on grass and to better alleviate the fatigue of several hours of golf. However, the rubber studs of the soles of many golf shoes in the prior art have lower strength and cannot play a good role in preventing water and skid, so that the soles cannot play a role in strongly grabbing the ground when a player swings to play a ball, thereby causing the conditions of unstable center of gravity, easy injury and the like,
