Achilles Tendinitis
Achilles tendinits is inflammation in and around the achilles tendon.  There two varieties on achilles tendinitis: noninsertional and insertional. In this case it is the orthotics job to correct the supinated foot.  Again re-aligning the tendon and preventing abnormal stresses on the tendon.  A custom orthotic will properly distribute body weight and gait function which will aid in the transfer of energy and shock through to the normal paths.
