How to treat a runner's sore achilles?

See below: Use a lift in your shoe to take pressure off the achilles, use ice to reduce inflamation, compression to control motion.

Orthotics: Achilles tendonitis is a mechanical problem as much as it is an overuse injury. First make sure you have supportive running shoes. If shoes are older than 6 mos, you may need to get shoes for overpronators. If you have good supportive shoes than the next step is good orthotics that control excess pronatory motion than causes torque on achilles' tendon. Physical therapy as adjunct therapy.
