Definitions

• the present invention concerns a non-slip tread with alveolar structure, applicable to the footwear sector, having holes communicating with internal transverse channels for lateral outflow.
• the part of the sole placed on the ground has a tread consisting of designs with raised parts of varying depths obtained by moulding that, by penetrating and adapting to the ground, ensure good grip. Even if they are designed in advance, the aforesaid raised parts do not however ensure a good grip of the shoe on the ground if this is a smooth, wet surface, because their presence reduces the contact surface of the sole with the said surface and holds water in the cavities.
• non-slip properties of a sole are generally given by the type of material with which they are made, which must be soft rubber, and by the design or pattern of the tread.
• tread designs or patterns must be specially designed to facilitate the outflow of as much water as possible from them during compression of the sole on wet paving.
• this footwear has a sole with a completely smooth tread that has small notches made in the sole that, normally but not exclusively being made of rubber, causes, during normal walking, opening of the said notches that spread their entire surface over hard, wet paving and suck up the water beneath so favouring direct contact of the tread with the paving, but, at the same time, reducing the contact surface with the ground.
• the soft rubber (or similar material) contact surface of the tread necessary for good grip on the ground, is almost non-existent in the said document, since almost the whole surface of the tread is occupied by the cotton fibre elements prepared for absorbing moisture, and these do not guarantee the right grip.
• the cotton fibres of the said elements lose part of their absorption capacity when they are glued to the tread and lose it completely in a short lapse of time in use on the ground, where one normally walks on water mixed with various other substances that clog the fibres that, on drying, can create exactly the opposite effect, that is, slipping.
• the said tyres are also manufactured of very soft rubber and have on their surface particular notches or grooves that, by favouring expulsion of water from them, prevent the formation of a film of water (aquaplaning) between the face of the tyre and wet asphalt or paving.
• the grooves, or notches, made on the surface of the tyres are used to create the space necessary for removing water from the part beneath the tyre. Maintenance of good grip is ensured by thick grooves or notches of the tread that run along the tyre axis.
• the relation between the surface of grooves or notches of the tread and the surface of the raised parts affects the entire contact surface of the tyre with the ground. Therefore, a large quantity of grooves or notches indicates lower tyre grip on a dry road in exchange for greater water removal capacity on a wet road.
• racing cars use two types of tyres: one smooth, to be used on a dry road, which fully exploits its entire surface in contact with the ground, the other grooved to varying degrees, to be used when the road is wet because it has the ability to remove the water present on the ground, so preventing aquaplaning.

• the present invention concerns a non-slip tread (1 ) for footwear having, in correspondence of the heel and the front half-sole, two areas with alveolar structure whose cells consist of walls (2) converging on a hole (3) to form a funnel-shaped surface.
• Each hole (3) is a through hole, that is, it passes right through the thickness of the tread (1) and communicates with a transverse channel (4) made inside the tread ( 1).
• alveolar structure means a structure consisting of cells or concamerations of any shape having walls (2) converging on a hole (3), to simulate a funnel-shaped surface, in which water can penetrate and be pushed or conveyed into a transverse channel (4) to then flow out sideways.
• the particular alveolar structure of the tread ( 1) in which the walls (2) converge on the holes (3) to produce a funnel-shaped surface ensures that during normal walking on hard, wet surfaces one does not slip because, during compression of the foot, the said structure allows the water being walked on to be pushed to the inside of the sole, which, on flowing through the hole (3), flows into the internal transverse channel (4) to then flow outward sideways.
• the water thanks to the funnel-shaped surfaces of the alveolar structure of the tread ( 1 ) that get squashed to the ground and to their consequent widening on the ground due to compression, is pushed into the hole (3) to then flow into the internal transverse channel (4) and flow outward sideways.
• the internal transverse channels (4) are therefore drainage for the water that the tread (1) of the sole accumulates inside it.
• the funnel-shaped surfaces of the alveolar structure of the tread (1) that get squashed to the ground during compression of the foot on the ground and the consequent push of the water towards the inside through the holes (3) ensure that the tread (1) has a better grip on wet ground and gives the user of the sole provided with the present invention better balance.
• the alveolar structure of the tread (1) of the sole since it is made up of funnel-shaped surfaces and therefore without large protuberances, gives its user greater comfort on all types of surface, whether wet or dry.
• the procedure for making it is secondary as the said non-slip tread (1 ) can be a single body consisting of a tread (1) with alveolar surface and internal transverse channels (4) made on the profile, or it can consist of a tread (1) with alveolar surface glued to an intermediate sole on which transverse channels (4) have been made.
