Hong Kong foot is a colloquial term for a specific type of foot deformity prevalent in Hong Kong, characterized by a bony projection on the heel bone. This condition may be caused by overpronation, poor shoe fit, and repetitive stress on the feet. Symptoms include discomfort, pain, tenderness, and difficulty walking. Treatment options include stretching exercises, orthotics, and surgery in extreme cases. Prevention involves wearing proper fitting shoes, maintaining good posture, and engaging in regular stretching exercises to reduce the risk of developing Hong Kong foot.
