A normal functioning foot allows for movement and can supinate and pronate (form arch and lower arch, respectively) when necessary. This still applies to those who possess a structurally high arch and those that have “flat” feet. Regardless of the shape or size of your arch, there is still some degree of supination and pronation motions that is necessary for you to function optimally.
Controlled motion of the foot relies on an orchestration of muscular efforts, and is not limited only to the intrinsic muscles of the foot and ankle; optimal foot function also requires a synergistic effort from muscles throughout the lower leg, knee, and even the hip.
A limitation in motion in any of the joints of the lower extremity can translate to the foot, thereby leading to excessive Read the rest of this entry
