Description

technical field [0001] The invention relates to an air pressure fixing device for shoes, in particular to an air pressure fixing device for shoes which is inflated by an air pump. Background technique [0002] Generally speaking, most traditional footwear uses shoelaces as a tool for loosening and fixing the feet. However, footwear with shoelaces has many inconveniences in wearing. For example, when the shoelaces fall off during wearing activities, the shoelaces must be re-tightened to continue activities, causing inconvenience and time wastage in activities. Furthermore, wearing footwear with laces is potentially dangerous. For example, when the shoelaces are accidentally loosened, it is easy to cause others to step on them and trip them, and they may also be caught in the gaps of escalators, bicycle chains or motorcycle pedals, etc., which may easily cause accidents. In addition, long-term wearing of footwear with laces tends to put excessive pressure on the feet, causin...

AI Technical Summary

Problems solved by technology

For example, when the shoelaces are accidentally loosened, it is easy to cause others to step on and trip, and it may also be involved in the gaps of escalators, bicycle chains or motorcycle footbolts, etc., which may easily cause accidents

In addition, long-term wearing of footwear with laces tends to put excessive pressure on the feet, causing discomfort to the wearer

[0003] A small number of traditional footwear use other methods as a tool to loosen and fix the feet, such as: Velcro felt or sock-style shoe body. However, the Velcro felt is not fixed enough and easy to fall off. Long-term use will make the Velcro felt sticky Falling, causing inconvenience in activities, and it is not suitable for wearing when exercising

The sock-style shoe body is not enough to fix the foot, and it cannot be adjusted according to the needs. Long-term use will easily cause the sock-style shoe body to loosen, which cannot meet the needs of fixing the foot.

[0004] On the other hand, the opening size of general traditional footwear is mainly designed according to its functionality. For example, sports shoes usually have a small opening design, so as to provide better coverage and avoid the However, such a small shoe mouth design often makes it difficult for the user's feet to penetrate into the shoe. If force is applied to open the shoe mouth to facilitate penetration, it will cause the shoe mouth to loosen and lose its coverage The effect of protection; for example, casual shoes usually have a large opening design for the user to put on and take off easily. Risk of injury to user's feet or damage to shoes
