Abstract

A sandal that uses a pump and bladder system to provide foot arch support a user. The sandal uses a strap system that defines a pump and a tubing system that attaches to the front and instep of a sandal. The instep of the sandal defines an air bladder that connects to the tubbing system. The air bladder inflates and provides arch support to a user of the sandal.

Description

TECHNICAL FIELD

The present invention pertains generally to the field of footwear. It is a sandal that provides an adjustable arch support that is adjusted using air pressure.

BACKGROUND OF THE INVENTION

Sandals, in their simplest form, are an open type of footwear consisting of a sole held to the wearer's foot by straps going over the instep. Sandals leave most of a user's upper foot exposed. Sandals are worn for comfort, economy, and sometimes as a fashion choice.

Soles of sandals are typically flat and have no arch support. Yet some sandals may have arch supports, yet the arch supports will be fixed and not adjustable. A fixed arch support may comfort the person for whom it was designed for, yet it will be of great discomfort for anyone else wearing the sandal.

The arches of the foot, formed by the tarsal and metatarsal bones, strengthened by ligaments and tendons, allow the foot to support the weight of the body in the erect posture with the least weight.^{1 1}Available at https://en.wikipedia.org/wiki/Arches of the foot,, Wikepedia: Arches of the Foot, seen on Apr. 29, 2019

Ailments that are caused by improper arch support are heel pain, over pronation, Morton's toe difficulties, Posterior Tibial Tendonitis, and Plantar Fasciitis. The referenced ailments are treated by providing orthotics that provide arch support.

Orthotics are expensive and cost prohibitive to some whom would choose to wear them. The cost associated with orthotics and the economic aspects of sandals go against providing orthotic devices to those whom choose to wear sandals on a regular basis. Most sandals provide little to no arch support.

The present invention is a sandal that will use a pump and bladder system to manually provide support to a user's foot arch. The sandal of the present invention will be an inexpensive alternative to custom orthotic sandals, if any exist.

BRIEF SUMMARY OF THE INVENTION

The present invention is directed to a sandal that uses a pump and bladder system to provide support to a user's foot arch.

The sandal comprises of a sole that has a front section, an instep section and a rear section, and a strap system that is attached to a sole at positions that correspond to the front and instep sections. A pump is attached to the strap system. An air bladder is attached to the sole at the instep section that will correspond to a user's foot arch. A tubing system connects the pump and to the bladder. The tubing system allows air to pass from the pump to the bladder. The pump will have an integral manual air release valve.

An object of the present invention it to provide a sandal that will have an adjustable arch.

Another object of the present invention is to provide a sandal that will prevent foot ailments.

Yet another object of the present invention is to provide a sandal that will help treat foot ailments.

Still yet another object of the present invention is to provide an inexpensive orthotic device.
