At heel contact, sufficient friction is needed to prevent the foot from doing what?

At heel contact, sufficient friction is needed to prevent the foot from doing what?

• A. Slipping forward
• B. Dorsiflexing
• C. Plantarflexing
• D. Everting

Answer: (A)

During heel contact, the body’s forward momentum tends to push the foot forward across the ground. Friction between the shoe and the ground provides the necessary resistance to that tendency, keeping the foot from sliding ahead and allowing stable weight acceptance as the stance leg supports the body. If friction is insufficient, the foot would slip forward, disrupting balance and the smooth transition into the next phase of gait. Dorsiflexion, plantarflexion, and eversion describe ankle and subtalar movements driven by muscles and joint mechanics, not the immediate need for frictional resistance at contact.
