DE2336314A1 - Foam plastics inlay for shoe heels - is fitted inside insole to evenly distribute load when walking or running - Google Patents

Abstract

The downwardly expanded inlay which has the shape of a small heel is beneath the support wedge which is stuck onto the sole and is enclosed by a wide edge which ensures that even when walking up an incline, the heel always remains in the centre of the shoe. The insole has incisions set transversely to the tread across the foam inlay so that the insole can expand downwards under pressure of the heel. Since the foam inlay is concealed, it remains in place even after long wear.

Sole part

The invention relates to a sole part which provides the user with a safe and particularly pleasant, soft walk Shoes allowed.

It is known to use a rubber heel to soften the hard impact of a heel on the floor.

It is also known to avoid pressure points on the feet by using soft insoles in a shoe.

The present invention has for its object to mitigate the hard impact of the paragraph on the ground as well as the heel in the shoe not only flexible, but at the same time to be supported so that the foot as in a Trough and thus the load of the body is transferred to the entire heel surface.

The object is achieved according to the invention in that the support wedge of the sole part has a over its entire height Contains foam insert that widens downwards and resembles a small paragraph and covers the insole this foam insert is continuous and perpendicular to the direction of travel Has lying incisions.

The foam insert catches when the heel is put on impacts on the floor. The downward expanding foam insert causes the Bumps from the foam insert widened outwards and the heels despite being flat Surface of the foam insert lying under the weight of the body like in a hollow shell. This deformation can be felt particularly clearly when the insole over the foam insert incisions at the same time has transversely to the running direction, so that at this point the insole under the pressure of the heel yields downwards can. Nevertheless, the remaining all-round edge of the support wedge around the foam insert made sure that, despite the flexibility of the foam insert, the heel is always in the middle of the shoe is held. Since the foam insert is hidden in the support wedge, it can also be used for long periods of time not gush out to the outside. In addition, a

even processing of the sole part on its outer surfaces is possible.

The drawing gives a sole part according to the invention, for example again, namely shows:

Fig. 1 the sole part in longitudinal section along the line I-I of Figs. 2 and

Fig. 2 the same sole part in plan view.

Only a small part of the insole is shown in both figures.

A support wedge 2 is glued to an outsole 1 and has a foam insert 3 below the heel, which widens downwards, but otherwise has a shape similar to a small paragraph. All around the foam insert 3 remains on the support wedge 2 a wider Edge 4, which ensures that the heel is always in the middle of the Shoe remains.

The insole 5 arranged thereon points over the foam insert incisions 6 lying transversely to the running direction.
