The cast above show the typical Root Balance Technique of Forefoot Varus Feet. With this foot type, the maximum support is under the first metatarsal. Remember you need first metatarsal plantar flexion for normal propulsion. Having possibly too much pressure under the first metatarsal can:
- Dorsiflex the First Metatarsal with gradual development of bunions or hallux limitus/rigidus
- Dorsiflex the First Metatarsal causing Apropulsive Gait (not allow normal first metatarsal plantarflexion.
- Dorsiflex the First Metatarsal causing Sagittal Plane Blockade with Hip/Low Back Problems
- Dorsiflex the First Metatarsal producing Lateral Instability with compensation.
