Mariners Taijuan Walker left the game last night with an injury to his tibialis posterior tendon, this muscle controls how much your foot rolls to the inside or "pronates". Orthotics can help control pronation, and decrease the load put through the insertion point of that tendon.
Having foot pain while competing in sports, ask us how we can help!
