Abstract
A shoe providing a massaging effect for a wearer of the shoe includes a sole bladder containing a fluid which can flow within the bladder as a wearer shifts weight in the shoe and at least one flow passage extending from the bladder into a shoe upper adjacent a portion of a wearer's foot and arranged in conjunction with the bladder so that fluid from the bladder will flow through the passage upon at least a particular weight transfer on the bladder. Preferably a flow passage is provided around the heel portion of the shoe and also at locations forwardly of the heel portion of the shoe. The fluid in the bladder is replaceable so that a cooling fluid or a warming fluid can be placed in the bladder. The bladder can also contain recessed portions positioned to relieve pressure on particular areas of a wearer's foot.
Claims22
A shoe which provides a massaging effect due to fluid flow in the shoe during use of the shoe, comprising:
- a shoe sole;
- a shoe upper;
- a bladder in the shoe sole extending from a heel portion of the sole to a toe portion of the sole;
- a reaction fluid within the bladder wherein the reaction in the fluid adjusts the temperature of the fluid;
- means for replacing the reaction fluid within the bladder;
- fluid flow means extending from the bladder into the shoe upper to be adjacent a portion of the foot in the shoe upper and in fluid flow communication with the bladder;
- wherein fluid will flow from the bladder into and through the fluid flow means as weight is shifted in the shoe on the bladder to stimulate and massage at least the portion of the foot of a wearer of the shoe adjacent the fluid flow means.
A shoe which provides a massaging effect due to fluid flow in the shoe during use of the shoe, comprising:
- a shoe sole;
- a shoe upper;
- a bladder in the shoe sole extending from a heel portion of the sole to a toe portion of the sole;
- fluid within the bladder;
- a heel fluid flow means including a flow passage extending from the bladder upwardly along a rearmost portion of the heel of the shoe upper and branching into two heel side flow passages which extend around the heel and back to the bladder;
- wherein fluid will flow from the bladder into and through the heel fluid flow means as weight is shifted in the shoe on the bladder to stimulate and massage the heel of the foot of a wearer of the shoe adjacent the heel fluid flow means.
A shoe which provides a massaging effect due to fluid flow in the shoe during use of the shoe, comprising:
- a shoe sole;
- a shoe upper;
- a bladder in the shoe sole extending from a heel portion of the sole to a toe portion of the sole;
- fluid within the bladder;
- a side fluid flow means including a side fluid flow passage extending upwardly from the bladder at a first position forwardly of the heel portion of the sole and returning to the bladder at a second position also forwardly of the heel portion of the sole and spaced from the first position;
- wherein fluid will flow from the bladder into and through the side fluid flow means as weight is shifted in the shoe on the bladder to stimulate and massage the side of the foot of a wearer of the shoe adjacent the side fluid flow means.
A shoe which provides a massaging effect due to fluid flow in the shoe during use of the shoe, comprising:
- a shoe sole;
- a shoe upper;
- a bladder in the shoe sole extending from a heel portion of the sole to a toe portion of the sole;
- fluid within the bladder, the bladder including pressure relief areas isolated from fluid within the bladder to provide pressure relief for portions of a wearer's foot needing such relief;
- fluid flow means extending from the bladder into the shoe upper to be adjacent a portion of the foot in the shoe upper and in fluid flow communication with the bladder;
- wherein fluid will flow from the bladder into and through the fluid flow means as weight is shifted in the shoe on the bladder to stimulate and massage at least the portion of the foot of a wearer of the shoe adjacent the fluid flow means.
An insert for a shoe to provide a massaging effect to a foot placed in the shoe, comprising:
- a bladder for insertion into a shoe to fit substantially coextensively under a foot placed in the shoe and having a heel portion and a toe portion;
- fluid within the bladder;
- side fluid flow means in fluid flow communication with the bladder including a side fluid flow passage extending upwardly from the bladder at a first position forwardly of the heel portion of the bladder and returning to the bladder at a second position also forwardly of the heel portion of the bladder and spaced from the first position, said side fluid flow means adapted to fit between the foot placed in the shoe and a shoe upper;
- wherein fluid will flow from the bladder into and through the side fluid flow means as weight is shifted in the shoe on the bladder to stimulate and massage at least the portion of the foot of a wearer of the shoe adjacent the side fluid flow means.
