Running Glossary

Gait Cycle:   The cycle begins when one foot hits the ground and ends when that same foot hits the ground again.  Its the focus of when your heel hits the ground and the toe-off position.

 

Pronation: is the three dimensional motion of the forefoot.  The foot first rolls inward, then rolls to flatten out.  Pronation occurs in the walking process and tends to cause the arch to drop.

 

Over Pronation: occurs when the foot rolls inward and the arch drops to flatten out.  The foot collapses, causing the foot to flatten, and adding additional stress to other parts of the foot.

 

Supination: is the three dimensional motion of the foot that tends to create a high arch in the foot.

 

Neutral Position: is the ideal state of a foot halfway through the gait cycle.  The foot is neither pronated nor supinated.  The key bones in the foot are “locked”.  The result is optimal power, stability, and a minimizing of eccentric motion, which stresses hips, knees and back.

 

Elongation: when the foot is unstable and constantly moving creating friction.  This movement is known to increase the possibility of heel bursas and blisters.

 

Support Shoe:  Generally has a more dense foam throughout the inside arch area to support those that naturally pronate. Defined on the shoe with a grey discoloration.

 

Motion Control Shoe:  Meant for those that over pronate, with heavy stability.  Also has discoloration on the inside of the sole, but could also have a "plastic" looking support.

 

Neutral shoe:  Meant for those that have a neutral gait cycle and those that supinate.  Basic support throughout the shoe.

 

Shoe Size:  Widths run from AA-6E depending on the brand.  AA being the most narrow, 6E being the widest.

Mens STANDARD width: D

Women's STANDARD width: B

Men's WIDE: 2E+

Women's WIDE: D+

 

Plantar Fasciitis:  inflammation caused by excessive stretching of the plantar fascia. Will often lead to heel pain, heel spurs and/or arch pain.  Over pronation (or flat feet) is the leading cause of plantar Fasciitis.

 

Shin Splints:  Shin splints result from the muscle pulling away from its attachments to the bone.  *** shin splints are most often caused by over pronation.  Infrequent shin splints are typically caused by over training and under preparation.
