A foot engagement device includes a generally U-shaped portion having an inner edge, an outer wall, and a tapered upper surface extending from the inner edge to the outer wall. The upper surface tapers between 1 degree and 45 degrees from the inner edge to the outer wall.

A method and apparatus for dynamically altering a height of a sole assembly of an article of footwear uses an actuator having a retraction assembly and a traction assembly. A wedge is moved to different positions within a groove formed in the sole assembly. A user evaluates the performance of the footwear with the wedge at different positions while performing an activity. The user evaluations help determine an optimal height of the sole assembly.

There is provided an insole for a sport footwear, the insole comprises: a forefoot portion comprising an incliner for inclining a foot of a wearer towards an outer side of the insole, a midfoot portion having an arch extending from an underside of the insole, and a rearfoot portion comprising an incliner for inclining the foot of the wearer towards the outer side of the insole. Such an insole can be effective for maintaining a linear motion of the knee of the user. Moreover such an insole can be effective for maintaining the foot of the person inclined outwardly. Thus, the body weight of the person can also be shifted outwardly, which improves balance.

Methods for providing footwear configured to treat leg length discrepancy include manufacturing a plurality of footwear members. Each footwear member has a sole thickness, with sole thicknesses of the plurality of footwear members spanning a predetermined range of thicknesses. A corrective pair of footwear may be formed by selecting a left member having a first sole thickness and a right member having a second sole thickness, wherein the difference between the first and second sole thicknesses corresponds to an amount of leg length discrepancy to be corrected.
