Description
Technical Field
The invention relates to the field of racing equipment, in particular to a pair of racing shoes with synchronously adjusted length and width.
Background
In recent times, as people's lives get better and better, various racing sports appear in the lives of the public, wherein the racing sports on ice, for example: skating, skiing, and dry-land racing-type sports, such as: roller skating, the type of sports that needs to be accomplished with the aid of special racing-type shoes, has also evolved from adult sports to civilian sports that will participate at all ages.
In the existing market racing shoes, users of different ages and foot sizes can only buy shoes of different sizes correspondingly mostly according to the feet of different ages and different sizes, and for people such as young children, the foot sizes can also change rapidly due to the fast growth speed, so that the users need to continuously replace and buy shoes of proper sizes, which is easy to cause economic burden and not environment-friendly.
Of course, many adjustable shoes for racing exist in the prior art, but such shoes are either only capable of adjusting the longitudinal length and not capable of adjusting the width, and the feet with different lengths can also change the width, for example, the foot shape of a child will gradually widen as the length increases, for a fierce racing, if the length can be adjusted independently, if the left and right widths of the feet cannot be tightly wrapped, the shoes with the longitudinal length and the left and right widths can be adjusted independently, if the shoes with the longitudinal length and the left and right widths can be adjusted simultaneously in high-speed sports, the feet can be twisted or fallen and injured due to the left and right displacement of the feet in the shoes, and if the shoes with the longitudinal length and the left and right widths can be adjusted independently, when the purpose of adjusting the length and the width is needed, the shoes with two different actions can be adjusted, and in the fierce racing, as the shoes with adjustable shoes are often matched with a plurality of complicated parts to achieve the purpose of adjustment, the shoes are easy to loosen and deform after being worn for a long time, and at the moment, the shoes need to stop again to be adjusted again. The adjustment performed twice obviously wastes time for racing sports, and is inconvenient to operate, troubles are caused to production due to complex part matching, and the reliability of mechanical properties of the parts is greatly reduced.
Accordingly, there is a need to provide a racing shoe with simultaneous length and width adjustment to address the above problems.
Disclosure of Invention
