Boat shoe

A shoesole having a tread side wherein there is means at the edge of the tread side comprising spaced, parallel, continuous, uninterrupted outer and inner ribs, said outer rib protruding perpendicularly from the bottom at the edge and the inner rib protruding perpendicularly from the bottom and being of lesser height and means on the surface of the tread side bounded by the inner rib comprising nubs distributed in spaced, parallel rows transversely of the sole and spaced apart in each row and said nubs being so dimensioned as to be more yieldable to bending in a direction longitudinally of the sole than transversely thereof.

A shoesole having a tread surface characterized in that there is a continuous, uninterrupted wiper blade on the tread surface circumferentially of the tread surface in the form of a rib projecting perpendicularly from the tread surface and within the area defined by the wiper blade a non-skid surface defined by a plurality of longitudinally and transversely-spaced, uniformly-distributed protrusions which have greater flexibility longitudinally of the sole than transversely of the sole.

A shoesole having a side structured to be a tread surface and a side structured to be an attaching surface characterized in that there is means protruding from the tread side defining a flexible wiper blade extending continuously, uninterruptedly along the edge of the sole and means protruding from the tread side within the area of the sole bounded by the blade comprising a plurality of longitudinally and transversely-spaced, uniformly-distributed friction-engendering elements of greater flexibility longitudinally of the sole than transversely of the sole.

A shoesole having a tread side bounded by an edge face characterized in that there are means on the tread side defining a continuous, uninterrupted rib circumferentially of the tread side and inwardly thereof a second rib which is of lesser height perpendicular to the tread surface than the first rib, said ribs defining a continuous groove in the tread side adjacent to the edge and means coextensive with the surface areas of the tread side at the forepart and heel end bounded by said ribs in the form of a plurality of longitudinally and transversely-spaced, uniformly-distributed nubs which have greater flexibility longitudinally of the sole than transversely of the sole.

A shoesole having a tread side bounded by an edge face characterized in that there are means on the tread side defining a first continuous, uninterrupted rib and inwardly thereof a second continuous, uninterrupted rib which is of lesser height perpendicular to the tread side than the first rib and of lesser transverse width than the first rib, said rib defining a continuous groove in the tread side adjacent the edge and a plurality of longitudinally and transversely-spaced nubs coextensive with the surface areas of the tread surface at the forepart and heel ends bounded by said ribs, said nubs being distributed in longitudinally-spaced, parallel, transverse rows with spaces between nubs and with the nubs in alternate rows alternating with the spaces in adjacent rows and wherein the nubs have greater flexibility longitudinally of the tread surface than transversely thereof.

A shoesole having a tread side characterized in that it is structured at its edge with continuous, uninterrupted wiping means peripherally of the tread side operable by the lateral movement of the shoesole on the surface upon which it rests to wipe the surface dry and a plurality of transversely and longitudinally-spaced, uniformly-distributed friction-engendering means coextensive with the tread surface inwardly of said wiping means, said friction-engendering means having greater flexibility longitudinally of the sole than transversely thereof.

A shoesole having a tread side, continuous, uninterrupted wiping means at the edge of the sole operable in the event of movement of the shoesole in a plane parallel to the surface upon which it rests to wipe the surface dry and a plurality of longitudinally and transversely-spaced, uniformly-distributed friction-engendering means coextensive with the tread surface inwardly of said wiping means, said friction-engendering means having greater flexibility longitudinally of the tread surface than transversely thereof.

A shoesole provided with a self-cleaning tread surface comprising transversely-extending, longitudinally-spaced, parallel rows of transversely-spaced nubs of greater flexibility longitudinally of the tread surface than transversely thereof between which there are spaces so that in adjacent rows the nubs in one row are situated opposite the spaces between the nubs in the adjacent row and so that the flexing of the nubs ejects foreign material which may tend to become lodged in the spaces between the rows of nubs.
