Support component 90 equally stably constitutes, wherein be shaped corresponding to heel space 46, and this rear side leg 90 ' and front side leg 90 at the look rear side leg 90 ' of support component 90 of direction of travel L " meet and form the seamed edge 94 of tumbling there at the front end of (on direction of travel L, the looking) in heel space 46.

The strengthening part 86 of preprocessing and the ventilation built in items 68 of preprocessing can be embedded in the injection mold cavity that is used for body 10 at the bottom of the injection moulding, wherein inject for example PUR of Shore hardness 58C for end body 10 in the injection moulding after closed mould.Can have the brace rod that is used for conduit wall 74 and be embedded into air inlet pipeline section 82 and pipeline section 84 slide blocks of giving vent to anger at this injection mold, the built in items 68 that is used for preventing to ventilate is pinched together during body 10 at the bottom of the injection moulding.

Because parts explosion has identical shaped recess and passage at the body of the middle end 10 shown in Fig. 7 with ventilation built in items 68.

Fig. 7 also illustrates to form and covers 52 inner sole 54, and it has by body of the middle end 10, exposes on the surface that end face forms 42 by strengthening part 86 and exterior wall parts 80 and interior wall parts 78 in case of necessity.

On perimeter sides, inner sole 54 is surrounded by the protuberance 50 of higher relatively formation.Make the supporting course 58 sole shapes ground of inner sole 54 constitute and correspondingly be matched with the thickness of supporting layer 64 in a preferred manner.Externally the surface 42 between wall components 80 and the protuberance 50 not only all has continuous band-like surface part 42 ' on the sole inboard 80 but also on the sole outside 20 in addition, makes supporting layer 64 pass through strengthening part 86 at the whole length upper support of wide interlude at body of the middle end 10 around ground along protuberance 50 thus.

Fig. 8 and 9 illustrates another the possible embodiment that is used for according to the strengthening part 86 at the end 12 of Fig. 2 or 3, and it is configured with the vent passages 30 by Fig. 1.From oblique upper strengthening part 86 is shown three-dimensionally in Figure 10, its effect is described with top embodiment in conjunction with Fig. 7 and identical by the known effect of MBT walking utensil.The profile at the end 12 and dark the strengthening part 86 of representing in shown in Fig. 8 and 9.

In heel area 16, flat strengthening part 86 46 extends and the internal interval ground at body of the middle end 10 extends below vent passages 30 in the back segment in toe zone 26 in arch of the foot zone 24 and looking on the direction of travel L along the heel space in body of the middle end 10.Because body of the middle end 10 in heel space 46 and surface the wall thickness between 42 in heel area 16 much smaller than in arch of the foot zone 24 and toe zone 26, embed by the known strengthening part 86 of MBT walking utensil and may cause vent passages 30 inadequate degree of depth in heel section 32.This is provided by Fig. 9 especially significantly, illustrates to vent passages 30 grey there.In order to overcome above-mentioned defective, make strengthening part 86 heel area 16 have corresponding to heel section 32, in vertical view the space 96 of the tunnel-shaped of V-arrangement.In order however also to guarantee the required bending strength of strengthening part 86, make strengthening part for example along making passage 98 separated galianconism 100 have the brace rod that on the bottom surface, extends.Although they reach in the heel soft-component 48, because its small height can not change performance or its characteristic of sole.Strengthening part 86 is made of stable material in heel area 16.

In sole, it is contemplated that according to Fig. 7, do not use ventilation built in items 68, but be formed for forming the key section 38 of passage " depression and the muscle by injection mold form its in segmental arc 72 connection and utilize the directly key section of formed channel on body 10 of the middle end of slide block.

When contacting, to make heel soft-component 48 pinched together on the one hand during with the walking of above-mentioned sole shown in the accompanying drawing with heel area 16, this reduces the impact to user's health significantly, also makes on the other hand to cover 52 and be out of shape on the direction of body of the middle end 10 in heel area 16.This causes being narrowed down by the part of the cross section middle end 10 and lid 52 or 58 restrictions of its supporting course, that be full of with air.Because roll extrusion on the ground is displaced in the toe zone 26 this narrowed cross-section by arch of the foot zone 24 on direction of travel L.The narrowing down of this heel area 16 is displaced to and causes air to be discharged by gas outlet 28 from vent passages 30 in the toe zone 26, and after the seamed edge upset of tumbling that forms in the leading section in heel space 46 by body of the middle end 10 in other words around the rib 94 of tumbling, lid 52 or inner sole 54 are lax in heel area 16, this is drawn into fresh air in the vent passages 30 by air inlet 20 thus because the elasticity of lid 52 or inner sole 54 causes cross section to become big again in the portion back of narrowing down.Therefore when walking, carry air by fan-type of the middle ends 12 ground with pure theory of mechanics.Air by the heating of the middle end is discharged by gas outlet 28, and fresh cold air sucks by air inlet 22.

Constitute as operculum 52 or inner sole 54, also the pin towards the user correspondingly pushes cold air ventilatively.
