A method for manufacturing stretch resistant plantar fascia support system is provided. The stretch resistant plantar fascia support system is adhesively applied to the foot of a patient for providing relief from plantar fasciitis. A portion of the stretch resistant plantar fascia support system is adhesively attached to the bottom surface of the foot for reducing stress on the plantar fascia.

A shoe sole includes a shock absorber that buckles when the shock absorber receives compressive force applied in a normal direction to a ground contact surface. When a load is applied to the shoe sole, the shock absorber starts to buckle in a state in which a stress occurring in the shock absorber is within a range from 0.15 MPa to 0.80 MPa and a strain of the shock absorber is within a range from 10% to 60%. When a time point at which a strain energy density of the shock absorber reaches 0.157 J/cm.sup.3 is defined as a specific time point, a maximum value of the stress occurring in the shock absorber until the specific time point is 0.80 MPa or less, and a tangential elastic modulus of the shock absorber at the specific time point is 5.00 MPa or less.

An orthotic support assembly includes a first orthotic support that is attachable to a sole of a shoe to abut a support surface upon which a user is walking. The first orthotic support has a rounded profile thereby facilitating the sole of the shoe to roll on the first orthotic support when the user walks. A second orthotic support is attachable to the sole of the shoe and the second orthotic support has a rectilinear profile to inhibiting the sole of the shoe from rocking on the first orthotic support when the user walks. A third orthotic support is attachable to the sole of the shoe and the third orthotic support has a trapezoidal profile. In this way the sole of the shoe is oriented level on the ground to facilitate a user with an unstable foot to walk in a level orientation.

A balanced insole structure with a massage function includes an insole main body and a connecting portion; the arch portion of the insole main body is provided with a convex portion matched with the curvature of the sole of the foot; the connecting portion is connected to two ends on the lower side of the convex portion, thus forming a stabilization cavity through their connection; and the insole main body is also provided with a massage protrusion on its upper surface. In the invention, the provision of the insole main body with the massage protrusion on its upper surface can realize the massage function of the insole.

Footwear for covering a foot of a wearer includes an outsole configured for supporting the foot of the wearer, an upper secured to the outsole and configured for covering the foot of the wearer, an insole located above the outsole within the upper, a midsole located above the outsole and below the insole and first and second laterally adjacent shanks located above the outsole and below the insole. The first shank angles forward and outward from the heel portion to a lateral side of the middle portion and the second shank angles forward and outward from the heel portion to a medial side of the middle portion to form an acute angle therebetween and provide balance and torsional stability for sides of the wearer's foot.

An insole comprising a shell component and a chassis component. The shell component comprises support bars that define framing apertures and the chassis component comprises undercut channels that define raised pod sections.

A non-removable insole, that is an integral part of a shoe or other footwear article, includes at least: a top layer, a middle layer, and a bottom layer. The middle layer of the insole has apertures or cavities, that define several discrete storage chambers within the insole. Each storage chamber stores a mixture of two or more particulate materials. The mixture includes one or more materials selected from Group A, which includes natural sand, synthetic sand, artificial sand, kinetic sand, silica, quartz. The mixture further includes one or more materials selected from Group B, which includes: powdered aluminum, powdered titanium, powdered zinc, powdered magnesia, powdered silver, powdered anti-bacterial agent, powdered metal, powdered talcum, grained cork, grained coal, grained wood.

A sockliner for a shoe may be formed to include an integral fabric skirt. The fabric skirt may remain loose from the sockliner along at least a portion of the periphery of the sockliner. The loose periphery of the fabric skirt may be used to join the sockliner to other shoe components, as in a strobel-type seam.
