Abstract
A spring shoe that includes a foot engaging portion, an upper platform, an intermediate platform, a first specifically configured spring, a lower platform, and a second specifically configured spring. The foot engaging portion engages the foot of the user. The upper platform is attached to the foot engaging portion. The intermediate platform is spaced vertically below the upper platform and is attached thereto by the first specifically configured spring. The lower platform is spaced vertically below the intermediate platform and is attached thereto by the second specifically configured spring. Each of the first and second specifically configured springs are a one-piece continuous wire formed into a pair of spaced-apart conically-shaped helical coils connected to each other by an integrally formed torsion bar.
Claims14
A spring shoe, comprising:
- a) a foot engaging portion for engaging a foot of a user;
- b) an upper platform attached to said foot engaging portion;
- c) a lower platform spaced vertically below said upper platform;
- and
- d) a spring arrangement connecting said upper platform to said lower platform, wherein said foot engaging portion has an inner sole for underlying the sole of the user and a toe engaging portion attached to said inner sole of said foot engaging portion for engaging the toes of the user so as to allow said spring shoe to be replaceably attached to the foot of the user, further comprising a coil spring disposed between said inner sole of said foot engaging portion and said upper platform, under the heel of the user.
A spring shoe, comprising:
- a) a foot engaging portion for engaging a foot of a user;
- b) an upper platform attached to said foot engaging portion;
- c) a lower platform spaced vertically below said upper platform;
- and
- d) a spring arrangement connecting said upper platform to said lower platform, wherein said upper platform has a periphery and substantially matches said inner sole of said foot engaging portion, further comprising an intermediate platform spaced vertically below said upper platform and substantially matches its configuration, and is attached thereto, by a first specifically configured spring of said spring arrangement, wherein said lower platform functions as an outer sole and has a periphery, and is spaced vertically below said intermediate platform, and substantially matches its configuration, and is attached thereto, by a second specifically configured spring of said spring arrangement, wherein each of said first specifically configured spring and said second specifically configured spring of said spring arrangement is a continuous one-piece wire having a thickness and formed into a first helical coil and a second helical coil that have loops with diameters.
