We have been seeing, addressing and treating this problem for years, far too many years. There are few things that frustrate us more than coaches and athletes who refuse to alternate their track workouts into the clockwise direction to help avoid the repetitious detrimental training effects of continued and repeated counterclockwise track training. 


Here is a study from 2000 that tends to validate a causal link to our point. The study confirms a statistically significant asymmetrical strength development in the hindfoot invertor and evertor muscle groups.

Orthotics and footbeds, they’re the same thing, right? This is a question that is posed to us all the time.  No, they’re not the same, but oftentimes one or the other can be appropriate. To explain the difference, we need to understand a little bit about foot mechanics.

The foot is a biomechanical marvel.  It is composed of 26 bones and 31 articulations or joints.  The bones and joints work together in concert to propel us through the earth’s gravitational field.  It is a dynamic structure that is constantly moving and changing with its environment, whether it is in or out of footwear. Problems with the bones or joints of the foot, or the forces that pass through them, can interfere with this symbiosis and create problems which we call diagnoses. They can range from bunions, plantar fasciitis, shin splints, TFL syndrome, abnormal patellar tracking, and lower back pain just to name a few.
