Improving Your Musculoskeletal Health... Starting With Your Feet

Hallux Limitus

When you show ProKinetics Insoles®: to a clinician totally immersed in traditional theories on foot mechanics (Roots), their first reaction typically is: "This insole will cause Hallux Limitus."

Hallux limitus is defined as the dorsal phalanx colliding with the metatarsal head.

Some people suffer from hallux limitus or hallux rigidus, but ProKinetics Insoles® are not likely to cause this condition.

As demonstrated with the model to the left, in the case of the hyperpronating foot, when placed in its weight bearing STJ neutral position, the first ray elevates. This fact is beyond contention, and can easily be verified by simply placing the foot in weight bearing STJ neutral. (place pointer over picture)

Dr. Vladimir Janda demonstrated that an exercise akin to picking up a towel with your feet but without curling your toes (Janda small-foot exercise) raises the arch, and externally rotates the leg. Starting from a STJ neutral position, this exercise brings the first metatarsal to the ground without collapsing the arch or internally rotating the leg.

ProKinetics Insoles
® place a small wedge (most commonly 3.5 or 6.0 mm) underneath the first metatarsal and big toe. This wedge, which does not extend to the second metatarsal, impacts the foot in two ways. 1] It causes a change in the timing of ground contact by the first metatarsal, and 2] it limits the maximum travel of the first metatarsal and big toe. It does not appreciably change the angular relationship between the first metatarsal and phalanx during the gait cycle. Place pointer over image to observe.

Practical experience: Thousands of patients have worn ProKinetics Insoles® for several years, and we have yet to receive a single report of the insoles causing pain in the joints of the first ray.
