🦶 Zone 1,2 – Heel Center (Central Calcaneus)

This zone is the center of the calcaneus — the rearward midpoint of the heel, typically the default point of contact in quiet standing.

🔬 Anatomical Role

  • Bears maximum weight during upright standing
  • Primary contact during walking heel strike
  • Directly loads the calcaneal tuberosity
  • No muscle originates or inserts directly beneath

🔬 Muscle & Tendon Support

Structure Type Action Relevance
Achilles tendon (insertion) Tendon Transfers calf muscle force Indirect rear support
Calcaneal fat pad Tissue Absorbs shock Primary cushioning
Plantar fascia (central band) Fascia Passive arch support Contributes to forward support

⚙️ Biomechanical Function

  • Excellent for load-bearing
  • Absorbs impact during heel strike
  • No rotational resistance or torque generation
  • Lacks proprioception detail — low feedback

🧠 Verdict

  • Torque Handling: ❌ None
  • Muscle Support: ✅ Passive only
  • Feedback Quality: ⚠️ Low
  • Stability: 🟢 Very high

🩰 Use in Dance

  • Used for:
    • Heel leads
    • Weight resets
    • Walking or neutral standing balance
  • Not useful for balance recovery or reactive poise

“Zone 1,2 is where weight goes to nap.”

✅ Summary

Zone 1,2 provides superb stability but no torque or feedback, acting like a parking brake for the foot. Great for stillness, but don’t expect action.
