3. The insole of claim 1 , wherein the peripheral sidewall has an outer perimeter, the relief has a longitudinal axis that extends toward a point in the outer perimeter of the peripheral sidewall, the peripheral sidewall has a tangent at the point in the outer perimeter of the peripheral sidewall, and the longitudinal axis of the relief is oriented with an offset angle of 80-90° from the tangent at the point in the outer perimeter of the peripheral sidewall.
4. An insole for footwear, the insole comprising:
a bottom surface having a perimeter;
a peripheral sidewall that extends upward from the perimeter of the bottom surface; and
a relief in the peripheral sidewall,
wherein the peripheral sidewall has an outer perimeter, the insole has a heel-support portion, and the relief is disposed in the heel-support portion and extends to the outer perimeter of the peripheral sidewall.
5. The insole of claim 1 , wherein the relief extends from the peripheral sidewall into the bottom surface.
6. The insole of claim 1 , further comprising a second relief, the bottom surface having a hole that is positioned, sized, and dimensioned to receive a heel pad, and the relief and the second relief being disposed on opposite sides of the hole from each other.
7. The insole of claim 1 , wherein the bottom surface has a toe-end portion and a heel-end portion disposed rearward of the toe-end portion, and at least a portion of the relief is disposed rearward of the heel-end portion of the bottom surface.
8. The insole of claim 1 , wherein at least one portion of the peripheral sidewall provides an arch support, and another relief is disposed in the at least one portion of the peripheral sidewall that provides the arch support.
9. The insole of claim 4 , further comprising a second relief in the heel-support portion of the peripheral sidewall and extending to the outer perimeter of the peripheral sidewall, the relief and the second relief defining a tab disposed between the relief and the second relief, and at least a portion of the tab being movable relative to the bottom surface.
10. The insole of claim 1 , wherein the bottom surface includes a bottom surface of a heel cap, and the peripheral sidewall includes a peripheral sidewall of the heel cap.
11. The insole of claim 1 , further comprising an insole pad, the bottom surface including a bottom surface of a heel cap, the peripheral sidewall including a peripheral sidewall of the heel cap, and the insole pad having a recess that is positioned, sized, and dimensioned to receive at least a portion of the heel cap.
12. The insole of claim 1 , further comprising an insole pad, the bottom surface including a bottom surface of a heel cap, the peripheral sidewall including a peripheral sidewall of the heel cap, and the insole pad having a plug that at least partially fills the relief.
13. The insole of claim 1 , further comprising a relief that has a radiused end portion.
14. The insole of claim 1 , wherein the relief includes a relief cut.
15. The insole of claim 1 , further comprising:
an insole pad; and
a heel cap coupled to the insole pad, the heel cap being more rigid than the insole pad, the heel cap including the bottom surface, the peripheral sidewall, and the relief.
16. The insole of claim 1 , further comprising:
a heel cap that includes the bottom surface, the peripheral sidewall, and the relief; and
an insole pad coupled to the heel cap, the insole pad being less rigid than the heel cap, the insole cap having a relief plug that is positioned, sized, and dimensioned to be received in the relief in the heel cap.
17. A set of insoles for footwear, comprising:
a first insole of a first size, the first insole including:
a first bottom surface having a perimeter;
a first peripheral sidewall that extends upward from the perimeter of the first bottom surface; and
a first relief in a first position in the first peripheral sidewall; and
a second insole of the first size, the second insole including:
a second bottom surface having a perimeter;
a second peripheral sidewall that extends upward from the perimeter of the second bottom surface, the second peripheral sidewall being less stiff than the first peripheral sidewall; and
a second relief in a second position in the second peripheral sidewall, the second position corresponding to the first position, and the second relief being smaller than the first relief.
18. The set of insoles of claim 17 , wherein the first peripheral sidewall includes a first material, and the second peripheral wall includes a second material that is less stiff than the first material.
19. The set of insoles of claim 17 , wherein the first bottom surface has a toe-end portion and a heel-end portion disposed rearward of the toe-end portion of the first bottom surface, at least a portion of the first relief is disposed rearward of the heel-end portion of the first bottom surface, the second bottom surface has a toe-end portion and a heel-end portion disposed rearward of the toe-end portion of the second bottom surface, and at least a portion of the second relief is disposed rearward of the heel-end portion of the second bottom surface.
20. The set of insoles of claim 17 , wherein at least one portion of the first peripheral sidewall provides a first arch support, the first relief is disposed in the at least one portion of the first peripheral sidewall that provides the first arch support, at least one portion of the second peripheral sidewall provides a second arch support, and the second relief is disposed in the at least one portion of the second peripheral sidewall that provides the second arch support.
