PLANTAR FASCIITIS
The excess motion of over-pronation stretches the Plantar Fascia more than normal, causing tears,
inflammation and pain. When the tears heal, they're covered with scar tissue, making the Plantar
Fascia less flexible and more susceptible to further tearing. The pain is usually worse after periods
of rest.
HEEL SPURS
Over-pronation causes repeated tearing of Plantar Fascia at the connection point with the calcaneus
(heel bone). Layers of calcium form a bone spur. The spur does not cause the pain, it is the constant
stress or tearing on the Plantar Fascia at the point of the Spur that causes the pain.
SHIN SPLINTS
What people commonly refer to as Shin Splints are mostly strains, inflammation or tears of muscle or
tendons, but they can progress into small stress fractures of the tibia (shinbone). The excess motion of
over-pronation often causes Shin Splints. The pain is usually sharp.
RUNNER'S KNEE
Over-pronation causes excessive inward rotation of the lower leg, which in turn causes the Patella
(kneecap) to pull to one side. The Patella undergoes excessive stress, which breaks down the cartilage
on the back side of the kneecap causing pain and inflammation.
ACHILLES' TENDONITIS
The combination of a tight calf muscle or shortened Achilles' Tendon and the excess (torquing) motion
associated with over-pronation can cause inflammation and pain in the Achilles' Tendon.
MORTON'S NEUROMA
The improper biomechanical action of over-pronation can cause the nerves to become pinched between two
metatarsal bones (usually the third and fourth). Pressure on the nerve can cause inflammation, sharp pain,
tingling or burning sensations. If the condition persists, surgery may be required.
