An active suspension orthotic support system is disclosed. The suspension orthotic support system comprises at least one variable resistance beam extending from a heel section to a mid-arch section of the footwear, wherein rotation of the variable resistance beam from a first position to a second position causes a resistance provided by the variable resistance beam to vary between a minimum resistance to a maximum resistance.

An insole having, a base layer, a top layer fixedly secured to the base layer, a middle layer comprised of the base layer and the top layer positioned between the base layer and the top layer, a pressure projection extending upwardly from within the middle layer and extending past an upper surface of the upper layer, the projection including a disc fixedly secured within the middle layer, an annular ring fixedly secured atop the disc, a circular metal insert fixedly secured atop the disc within the annular ring, the circular metal insert having a horseshoe-shaped aperture therein. The insole may also include projections either positioned proximate an inside arch and/or positioned proximate an outside arch. The insole may also comprise a projection positioned proximate to a midfoot region.

An insole having a magnetic propulsion insert, provided with magnets or magnetic charges inside thereof, which provides a magnetic distracting effect in the midfoot and the hindfoot of a user. The insole formed by two sheets is merged in the fore third, known as the forefoot zone leaving the sheets in the midfoot zone and the hindfoot zone separated. The magnetic propulsion insert is a structure formed by a sheet which bends in its midpoint to create two separate surface and with identical magnetic charges. These generate a propulsion effect by the force or impulse produced by the magnetic charges. In the rear thirds of the insole, the top sheet has charges in its bottom surface, and in these two thirds the bottom sheet has the same charges as the top surface. This is to generate the propelling effect in the foot heel of a user.

A tunable rigidity insole with interchangeable stiffeners includes an arch pad main body and three rigid stiffeners. The arch pad main body includes a set of first to third engaging holes, and at least one or two of these three rigid stiffeners will be selected to assemble into the engaging holes on the arch pad main body. The three rigid stiffeners provide supports to lateral longitudinal, central and medial longitudinal arch portions respectively. The first, second and third rigid stiffeners have at least two engagement members for each stiffener, and the engagement members have engagement extensions with a partial length component toward another engagement extensions at the end of stiffeners thereof respectively. The engagement members engage with the arch pad main body corresponding to the engaging holes respectively. By selecting and assembling different stiffeners, the present invention can have different rigidities of arch supports to match with various foot biomechanics and gait types in order to provide different arch supports thereto properly.
