Abstract

A thong style sandal with cleats comprising of a foot-bed with a foot strap and a sole having a plurality of removable cleats that extend out from the bottom of the outsole to define a ground-engaging surface for extra traction. The sandal includes a foot--strap attached to the front portion of the foot-bed with a toe post, and substantially arc-shaped side straps attached on opposing sides of the foot-bed, the ends of the foot-strap being anchored to the outsole. The sandal with cleats provides ground engaging traction while providing extra comfort as it allows the foot to remain at an ambient temperature by allowing the foot to breath in open air as the greater part of the foot is exposed to the environmental elements. The sandal conforms closely with the foot that provides a stable platform during sporting activity. The sandal has a plurality of sockets for securing the cleats to the sandal.

Thong Sandal With Cleats Therefor

Description

This invention generally relates to footwear, specifically to a thong style sandal with removable cleats for use in sporting activity where extra traction is necessary.
Background Of The Invention Sandals constitute one of the earliest footwear known to man. Typically, sandals incorporate either a leather or rubberized sole which can be attached to the human foot by straps extending across the Achilles heel, and the top of the foot of the user.
Early sandals were designed for walking. Sandals however, have recently developed for more demanding sporting activities. More force and stress is applied to the sole, during the stopping and twisting moves during sports activities such as golf, hiking, climbing, etc.

Due to the recent commercial interest in sport sandals, there has become a need for a thong style sandal that is already familiar to the user that enhances the users ground stability by providing interchangeable cleats without sacrificing comfort.
Several types of sandals with cleats have been proposed but none currently reflect a thong type sandal with removable cleats- for example, in the following United States of America patents:
United States Patent 7,584,553 United States Patent 6,295,742 United States Patent 2,525,308 United States Patent 4,051,610 United States Patent 4,525,939 United States Patent 3,597,863 United States Patent 6,052,920 United States Patent D379709 United States Patent D477129 United States Patent D496523 Although such sandals have achieved considerable popularity and commercial success, there has been a continuing need for improvement. and nevertheless all the sandals heretofore known suffer from a number of disadvantages:
(a) Some current types of sandals have permanent molded in traction enhancing features, which really don't add much more than a typical sandal sole. Any sole with a semi aggressive groove tread pattern will have the same stability effect.
(b) Some current types of sandals that do have the removable cleats are basically just a running shoe with holes cut out of the shoe upper.
(c) With not having removable cleats you are hoping the elemental conditions do not wear down the sole. The sole is will eventually wear (d) down over time, and not having the ability to change and always have new cleats will lead to a loss of traction which defeats the purpose of the current types of sandals. Golf shoes have removable spikes for a reason it is so they can always be replaced ensuring proper traction on-going.
(e) The current types of sandals are only a one purpose use and cannot be altered to fit different applications or activities. Meaning you cannot change the use from golf cleats to hiking cleats to no cleats for everyday walking.
(f) The current types of sandals are one dimensional and only fit one type of individual's style preference not allowing another person to have a choice of a casual footwear product to compliment an individual style.
(g) Some traction enhancing systems are required to be strapped to your foot or a shoe making it very heavy and difficult to move.

Summary of The Invention The invention, an improved thong style sandal that provides comfort and stability, has a foot-bed, a thong foot-strap attached to the front portion of the foot-bed, side straps attached to the thong and to the opposite sides of the rear portion of the foot-bed, a toe post between the Hallux (Big toe) and the index toe and an outsole comprised of a plurality of cleats that mount into receiving sockets that allow the user to easily, and when necessary change the cleats. The cleat sockets are placed around the perimeter of the outsole and form a preferable cleat pattern, a cleat then may be mounted into the cleat socket. The cleat socket is embedded into the sole and is surrounded by the outsole and foot bed material not allowing it to be removed from the sandal. The cleat socket is a permanent part of the sandal and the socket shape may be changed to accommodate different cleat mounting types.

Accordingly several advantages of the invention are to provide an improved thong style sandal, to provide means of greater comfort, ground engaging traction, a better form of foot temperature control, ability to remove the cleats for use in everyday situations, and better terrain feel. By not having the foot fully incased with an Achilles heel strap it allows the user to maintain a means of control during sporting activity. Still further objects and advantages will become apparent from a study of the following description and accompanying drawings.

In operation the user places the left or right foot sandal on the appropriate human foot with the toe post between the Hallux (Big toe) and the index toe. When the user steps into the sandal and places their foot onto the foot-bed the sole is engaged to the ground. As the weight of the stationary human body and the forces of gravity is initiated the cleats firmly grip the ground surface and provide a stable planting that prevents sliding or twisting of the sole during the activity.
When not using the sandal during an activity the cleats do not fully engage as the human body's weight is not fully planted allowing the cleats solely to provide extra traction while walking on the ground surface.
