With reference to Fig. 1, sole is equipped with two spring assemblies, one of heel region, partly one of half sole, spring (7), spring (8) has all been compressed certain altitude in advance by housing, have prestress, spring can be a plate-shaped springs, also can be helical spring, spiral compression spring is better, spring material can be nonmetallic materials, as rubber etc., also can be metal material, general carbon spring steel wires or other steel wire of adopting, the specification of spring do not have strict restriction, but usual range is as follows: 1～6 millimeter of steel wire diameter, 7～80 millimeters of spring external diameters, the number of coils are 3～15 circles.Spring also can adopt cluster spring, promptly adds a less interior spring in the big spring again, as Fig. 6, refills a less interior spring (17) in the spring (7).Adopt cluster spring can make full use of space in the housing, reduce diameter of the housing and height.Under the certain situation of housing, can also be by increase and decrease or in changing the way of spring change elastic force, with this way person's that adapts to the different weight needs.The manufacture method of spring has three kinds: the one, and manual coiling, the 2nd, mechanical coiling, the 3rd, coiling on automatic torsion machine.The version of housing can be varied.Fig. 6 is a kind of version of housing, housing is made up of fixed cover (5) and sliding sleeve (6), slide over and be matched in clearance in the fixed cover, there is boss the sliding sleeve upper end, also there is boss the fixed cover lower end, sliding sleeve can slide up and down along fixed cover, but can not break away from fixed cover, can produce the effect that compresses spring in advance.

As Fig. 6, between sliding sleeve (6) and the fixed cover (6) is matched in clearance, and guide effect is arranged, and also has dustproof effect in addition.Fixed cover sliding sleeve appearance and size is unrestricted, general scope commonly used is that sectional dimension is not more than sole, width both height and that be not more than sole, fixed cover (5) and sliding sleeve (6) can be made by nonmetallic materials such as rubber plastics, manufacture method is to make mould earlier, on forcing press, suppress then, perhaps on injection molding machine, make.Fixed cover (5) and sliding sleeve (6) also can be by the metal material manufacturings, as aluminium sheet, iron plate etc.Manufacture method is to make earlier mould, blanking on stamping machine then, stretch forming on stretching-machine after this.Fig. 4 is the another kind of version of housing, fixed cover (13) is interior, sliding sleeve (17) outside, this mode can prevent that a spot of muddy water from entering in the shell, Fig. 3 is another version of housing, software partly (16) is arranged, when housing is flexible up and down in the middle of the housing, software partly can fold, and can prevent entering of muddy water fully.The sectional dimension of housing can be unrestricted, and it is more suitable generally to take off the row scope: the height that the sectional dimension of housing is not more than sole, housing is not more than the sole width.Software partly can have been made folding in advance, also can not be with folding earlier, and housing bottom also can be installed the contact of being convenient to change.The installation method of contact can have various, and as Figure 10, shown in Figure 11 to be contact fastening with screw (23), shown in Figure 5 is that contact (20) and sliding sleeve (21) are with being threaded.Shown in Figure 4 is that contact (19) directly is contained on the sliding sleeve (17), fastening by groove elastic force or frictional force.As Fig. 7, spring assembly can by a fixed cover (6) and up and down two sliding sleeves form, collet (13) is formed at the end in upper sliding sleeve and the footwear, as Fig. 9, collet (13) can be supported by big spring (8), also can be supported by spring less in the big spring (9), and collet floats in footwear, can play the clamping action to pin, the clamping force that little spring produces is comparatively suitable.

Suitably increase the sealing of housing, as reducing the slit or the gap of gas leakage, sole is opened the hole of some ventilations, just can form blower system, can promote the circulation of air in the footwear, and the big I of air quantity is adjusted by the method that changes gas leakage slit or gap.As Fig. 1, the passage of opening on the sole (15); Sliding sleeve during walking (3) moves up and down in fixed cover (5), when moving on the sliding sleeve (3), space in sliding sleeve (3) and the fixed cover (5) reduces a part of air and discharges from steam vent (15), discharge in gap another part air contacts partly from sliding sleeve (3) with fixed cover (5) between, the air by pore has just been reduced in the increasing gap, discharges with the moisture that changes the gap.

Advantage of the present invention is as follows: the energy-saving efficiency height, owing to adopt prestressed spring, cluster spring, not affecting in the situation easy to use, improved energy-saving efficiency greatly; Vibration damping is good, and protection pin and brain are injury-free; The footwear inner air flow is good, can in time discharge moisture in the footwear. Owing to solved ventilation problem, upper of a shoe can adopt the shoemaking new materials such as artificial leather, synthetic leather, thereby reduces cost. The collet that floats in the footwear is clamped pin, can not fill shoestring, wear off conveniently, and also good, comfortable and easy to wear to the adaptability of pin, owing to having reduced the wearing and tearing of footwear and having deflected, the abrading section is stressed evenly, and easy-abrasion part is changed convenient, and greatly improve the service life of footwear. Can obtain good social effect after the present invention applies, reduce many owing to wear the improper disease that causes of footwear, increase physical vigor.

No matter in daily life the present invention is applied widely, no matter man, woman, old, children can both wear,, or in work and motion, can both wear. Can manufacture cotton-padded shoes, the cotton in winter Boots also can be made the footwear boots of wearing spring and autumn, also can make the sandals worn summer, slippers etc.; the simplest form is only at heel a spring to be installed, and becomes elastic high-heeled shoes, as adds the big spring height; be installed at the end of parachute jumping boots, can greatly improve the protective capability of boots.

Optimum implementation as shown in Figure 1, the heel of a shoe position fills a spring assembly and comprises that a fixed cover (5), a sliding sleeve (3) and a spring (7), footwear half sole position fill a spring assembly, comprise a fixed cover (6), a low sleeve (4), a collet (13), two outer springs (8) and two inner springs (9) are arranged in the cover, collet is supported by inner spring, sole has pore (15), and ventilating system is arranged in the footwear, and contact (22) is arranged at the sliding sleeve bottom.
