BACKGROUND OF THE INVENTION [0001] Current shoes have many serious design problems or flaws that make them less desirable to consumers. Some of these problems relate to the difficulty in putting on a shoe. It would also be desirable if a shoe could be designed which could have beneficial effects to the wearer such as providing an energy return heel mechanism or providing improved insoles. [0002] U.S. Pat. No. 5,437,110 discloses an adjustable shoe heel spring and stabilizer which includes a spring as the upper side of a U-shaped member. A fulcrum is mounted below the spring at the end of a rack which extends through a hole in the bight of the U-shaped member. A gear on the opposite of the U-shaped member engages the rack. Rotation of the gear cause the rack to move longitudinally to adjust the position of the fulcrum under the spring. SUMMARY OF THE INVENTION [0003] An object of this invention is to provide an improved shoe which incorporates an energy return mechanism preferably one which is adjustable for people of different weight, spring preference and activity. [0004] A further object of this invention is to provide an adjustable insole for such a shoe. [0005] Other features of the invention include providing the capability of having shoes with variable thickness soles or weights and of structure which makes the shoe more comfortable and easier to put on and take off. [0006] In accordance with this invention a shoe which could be of any type including sandals, sneakers, etc. includes a shoe upper secured to a sole. The shoe upper is provided with an energy return heel mechanism in its heel portion. The mechanism comprises a spring lever which extends into the heel portion for receiving the heel of the user. The spring lever is pivotally mounted against a fulcrum whereby the downward force from the user's heel against the lever is resisted by the lever which imparts an upward force against the user's heel. The force applied by the lever is adjustable so that the desired force can be preselected by the user. [0007] The shoe may also incorporate an insole which provides variable support such as being inflatable and or being made of a memory foam. [0008] Other features of the shoe may include sets of shoes having different thickness soles or different weight soles. The shoe upper may be designed to facilitate putting the shoe on or taking the shoe off by having the heel top rolled backward and having the tongue rolled upward. Comfort may be provided by forming the toe box in a squared off shape both in plan and in elevation view. Stability may be provided by dimensioning the sole so that it is peripherally wider than the shoe upper at the toe box and peripherally around the hole upper.
