Adjustable sole support system
View Patent ↗A removable and adjustable insert for footwear has slots placed in the insole and/or midsole of the shoe to allow access to the arch and/or metatarsal and/or heel regions of the insole and/or midsole. In an embodiment, an insert placed into the arch insert slot that establishes how much the arch protrudes above the remainder of the top surface of the insole. One or more inserts are provided having different thicknesses so that the height of the arch can be varied by the user or at the direction of a third party, such as a doctor or a trainer.
1. A footwear support system comprising:
a molded insert insole comprising a semicircular arch along a central medial edge and an insole thickness with at least one first layer joined to at least one second layer, wherein the at least one first layer and the at least one second layer are configured to form a semi-circular arch insert slot between the at least one first layer and the at least one second layer, wherein the semicircular arch has a thickness of at least most of the insole thickness wherein the semi-circular arch insert slot at least partially underlies the semicircular arch; and
at least one arch insert, wherein the at least one arch insert is configured to fit into the arch insert slot, the at least one arch insert having a thickness and an outer edge surface, whereby the at least one arch insert engages the arch insert slot and the outer edge surface defines a continuous exterior edge of the insole when engaged with the arch insert slot, the insert of a pliable material, the insert comprising a semi-circular center portion wherein the thickness varies of lesser rate than a semi-circular outer section.
2. The footwear support system of claim 1 , wherein the at least one arch insert is semicircular.
3. The footwear support system of claim 1 , further comprising:
at least one metatarsal insert slot formed in at least one layer of the at least one first layer and the at least one second layer; and
at least one metatarsal insert, wherein the at least one metatarsal insert is configured to fit at least partially into the at least one metatarsal insert slot.
4. The footwear support system of claim 3 , wherein the at least one metatarsal insert slot extends over a portion of a metatarsal region of the insole.
5. A shoe which incorporates the footwear support system of claim 1 .
6. The footwear support system of claim 1 , wherein the at least one arch insert is a plurality of inserts of thickness between approximately 4 mm-8 mm.
7. A footwear support system comprising:
a molded insert insole comprising a semicircular arch along a central medial edge and an insole thickness with at least one first layer joined to at least one second layer, wherein the at least one first layer and the at least one second layer are configured to form a semi-circular arch insert portion between the at least one first layer and the at least one second layer, wherein the semicircular arch has a thickness of at least most of the insole thickness wherein the semi-circular arch insert portion at least partially underlies the semicircular arch; and
at least one arch insert, wherein the at least one arch insert is configured to engage the arch insert portion, the at least one arch insert having a thickness and an outer edge surface, whereby the at least one arch insert engages the arch insert portion and the outer edge surface defines a continuous exterior edge of the insole when engaged with the arch insert portion, the insert of a pliable material, the insert comprising a semi-circular center portion wherein the thickness varies of lesser rate than a semi-circular outer section.
8. The footwear support system of claim 7 , wherein the at least one arch insert is semicircular.
9. A shoe which incorporates the footwear support system of claim 7 .
10. A footwear support system comprising:
a molded insole having an insole thickness, wherein the insole comprises a semicircular arch along a central, medial edge of the insole, wherein the semicircular arch comprises a first thickness of at least most of the insole thickness, wherein the insole further comprises a semicircular slot about a lower surface of the insole along the central, medial portion of the insole, whereby the semicircular slot at least partially underlies the semicircular arch; and
at least one removable semicircular insert having a second thickness and outer edge surface, whereby the at least one insert engages the semicircular slot and is flush with the central, medial edge of the insole, the outer edge surface defining a continuous exterior edge of the insole when engaged with the semicircular slot, the insert of a pliable material, the insert comprising a semi-circular center portion.
11. The footwear support system of claim 10 , wherein the second thickness varies of lesser rate than a semi-circular outer section of the at least one insert.
12. A shoe which incorporates the footwear support system of claim 11 .
13. The footwear support system of claim 1 , wherein the semicircular arch thickness is greater than the insole thickness.
