Runner. high arches. i find my hip flexor and soleus muscles hypertrophied. can anyone relate foot structure to biomechanics?

See an orthopaedist: High arches themselves are common and do not necessarily correlate with problems. Consult with an orthopaedic surgeon and consider an evaluation with a physical therapist to see with their are aspects of your running style that need modifications.

Yes...: See a local podiatrist. We are all trained in this type of diagnosis and treatments.
