I had reached the stage of recovery where I could walk a couple of miles pain free and thought I was ready to resume a run-walk routine. I was wrong. Now I’m limping along again and reevaluating a lot of upcoming plans.
From the Dr. Foot Web site:
CAUSES OF ACHILLES PAIN
--The biggest contributing factor is ignoring the pain in the tendon.
--Achilles Pain commonly occurs from shearing and stretching forces placed on the achilles tendon. Excess Pronation (rolling over of the foot) causes extra strain on the tendon. Inflammation of the tendon is a common result along with tightening of the calf muscles.
--Sudden increases in training can lead to achilles tendonitis.
*--Excessive hill running or speed work.
--Inappropriate shoes. If the soles of the shoes are too stiff, this causes the forefoot to have limited movement. This can lead to increased tension to the achilles tendon.
--Studies have shown that excessive heel cushioning can be a contributing factor. Air filled heels are not very good for achilles tendonitis. If you wear a shoe that is designed to give greater shock absorption, what frequently happens is when the heel makes contact with the ground and continues to sink lower while the shoe is absorbing the shock. This causes the achilles tendon to be stretched.
*--Tight calve muscles.
*--Mechanical abnormalities of the feet such as over pronation.
*--Women who take up running are at a greater risk. This mainly affects women who wear high-heeled shoes, which effectively shorten the achilles tendon. When the individual then takes up running in "flat shoes," the achilles tendon is put
under increased tension.
