At least a portion of a heel strap 106 may alternatively, or additionally, extend laterally about an individual's heel. At least a portion of a heel strap 106 may alternatively, or additionally, extend medially about an individual's heel. The nature of the extension of heel strap 106 about an individual's heel may have a bearing on the manner in which an individual's foot 112 is biased by foot positioning device 100.

Orientation of heel strap 106 to extend posteriorly about an individual's heel may impart a moment M to the user's ankle about an axis extending substantially medially-laterally (substantially parallel to the frontal plane) relative to a user's ankle. Orientation of heel strap 106 to extend medially or laterally about an individual's heel or ankle may impart a moment M to the user's ankle about an axis extending substantially anteriorly-posteriorly (substantially parallel to the lateral plane) relative to a user's ankle.

Adjustment mechanism 108 may comprise any device configured to cause selective lengthening and shortening of heel strap 106. Adjustment mechanism 108 may comprise, for example, a strap adjuster, a triglide, a buckle, a bungee cord adjuster, a wind-up roller, or the like. Tag end 110 may be manipulated to shorten and/or lengthen heel strap 106. In one embodiment, tag end 110 is eliminated.

Heel strap 106 may be configured to cause a moment M in a counterclockwise direction (with reference to the illustration in FIG. 1), such that an individual's foot 112 is biased into a plantar flexion position. Alternatively, heel strap 106 may be configured to cause a moment M in any of a variety of directions, so as to bias an individual's foot 112 into any of a variety of desired positions, including for example: plantar flexion, plantar flexion with eversion, plantar flexion with inversion, and the like. Heel strap 106 may be configured to cause a moment M in any of a variety of directions upon removal of at least a portion of an individual's weight from an individual's foot 112. Heel strap 106 may be configured such that application of an individual's weight to an individual's foot 112 overcomes moment M, such that an individual's foot 112 can be oriented in a substantially neutral position with application of weight. Heel strap 106 may be configured such that application of an individual's weight to an individual's foot 112 overcomes moment M, such that an individual's foot 112 can be oriented in a substantially dorsal flexion position with application of weight.

In one embodiment, heel strap 106 is configured to apply a force between proximal strap 102 and distal strap 104. Force applied by heel strap 106 may be between about 44.0 N and about 222.0 N. Force applied by heel strap 106 may be between about 66.0 N and about 178.0 N. Force applied by heel strap 106 may be between about 89.0 N and about 133.0 N. Force applied by heel strap 106 may be between about 10% and about 40% of an individual's body weight. Force applied by heel strap 106 may be between about 15% and about 35% of an individual's body weight. Force applied by heel strap 106 may be about 25% of an individual's body weight. In one embodiment, heel strap 106 is configured to apply a force with any combination of the values recited herein.

Where heel strap 106 is an extensible material, decreasing the length of heel strap 106 may cause heel strap 106 to apply a greater force, while increasing the length of heel strap 106 may cause heel strap 106 to apply a lesser force. That is, the extensible material may have a spring rate, and the force applied by the extensible material may be directly related to the displacement of the extensible material multiplied by its spring rate. As a result, shortening heel strap 106 may cause greater displacement of heel strap 106, and thus greater force applied by heel strap 106. Lengthening heel strap 106 may cause lesser displacement of heel strap 106, and thus lesser force applied by heel strap 106.

For example, electronic device 216 may be oriented on the dorsal portion, medial portion, or lateral portion of shoe 212 or a foot (not shown). In such an embodiment, the force, pressure, and the like, imparted from shoe 212 or a foot (not shown) to the ball may be measured. In addition, velocity, acceleration, angle of swing, angle of foot, number of repetitions, and the like may be measured by this placement of electronic device 216. Alternatively, any of these factors may be measured through any orientation of electronic device 216.

In one embodiment, a ball used in athletic activities, such as a soccer ball, football, rugby ball, kick ball, or the like, may include an electronic device configured to measure at least one of the ball's speed, force, spin, velocity, trajectory, and the like.
