DESCRIPTION:
BRIEF SUMMARY
This invention relates to shoe soles, more particularly a sports shoe sole comprising a front sole portion and usually a heel portion, at least the front sole portion having projections extending downwardly from the shoe sole.
Shoes having soles of the type defined above are well known for use in sports where it is necessary to have good grip on a grass playing surface, for example all football games. One problem with shoe soles of this type is that under muddy conditions they become blocked with mud and lose their effectiveness to provide grip. The standard boot with screw-in studs often presents the wearer with turning difficulties and is known as a source of knee injury.
It is an object of the present invention to significantly reduce these disadvantages.
According to the present invention there is provided a shoe sole comprising a sole portion with a forward toe end and a rear end, an inner medial side and an outer lateral side, the shoe sole further including a plurality of blade-like projections extending downwardly from the sole portion, each projection extending downwardly to an elongated and relatively thin lower extremity, at least two of the projections being medial projections which extend from the vicinity of the medial side of the sole portion towards the lateral side and at least a further two of the projections being lateral projections which extend from the vicinity of the lateral side of the sole portion towards the medial side, at least one of the medial projections being angled relative to a generally longitudinal line from the toe end to the rear end of the sole portion so that an outer end nearer to the medial side of the sole portion is located forwardly of a centre end of the angled projection remote from the medial side of the sole portion, the angled medial projection thereby providing increased grip for the outside foot of a wearer during turning movement as a result of extending normal to or being relatively close to being normal to the direction of pushing force on the angled medial projection during such turning movement.
The expressions "inner medial side" or "inner medial edge" of the sole portion are used to refer to the side of the sole portion which is nearer to the sole portion to be worn on the other foot of the user. Thus, looking down on the right shoe being worn on the foot, the "inner medial side" and "inner medial edge" of the sole portion will be at the left side, and vice versa.
Each projection has a height defined as the distance from the sole portion to the lower extremity and the height of the projections nearer to the toe end may be less than the heights of those projections closer to the rear end. Preferably the height reduction is progressive towards the toe end. This improves the "feel" during running.
At least one of the medial projections and preferably the ones nearest the toe end, may have an outer corner at the end of the lower extremity which is nearer to the medial side of the sole portion which is displaced towards the lateral side of the sole portion and away from the line of the medial side. This enables a ball to be kicked with the inside of the foot so as to loft the ball without the medial projections striking the ball first.
There may be provided a transverse flexing zone across the sole portion at the location of the ball of the foot, the transverse flexing zone not having any projections thereon nor containing portions of any projections. This construction enables the sole portion to bend across the ball of the foot thereby enabling the foot to bend along its natural transverse flexing line.
In one possible embodiment suitable for most sports, each of the medial and lateral projections is angled obliquely across the sole portion with the end of each projection nearer to the medial side being located forwardly and closer to the toe end of the sole portion.
In an alternative possible embodiment suitable particularly for sports in which there is much forward pushing or forward acceleration, at least one of the medial projections and at least o
