Limited mobility of the ankle could also result in abnormal gait patterns. When walking at an average speed of ambulation (~1.25 m/s) the ankle joint requires at least 10-20 degrees of plantar flexion. Limited ankle plantar flexion may result in decreased push off force, which could lead to shorter step length.
The final stage of casting is to correct the equinus. After fully abducting the forefoot with spontaneous correction of the hindfoot, an attempt is made to bring the ankle up and into dorsiflexion. The foot must have the ability to dorsiflex to at least 10 degrees past 0 (neutral, or L position), although 15 degrees or more is better and preferred.
Dorsiflexion of the foot: The muscles involved include those of the Anterior compartment of leg, specifically tibialis anterior muscle, extensor hallucis longus muscle, extensor digitorum longus muscle, and peroneus tertius. The range of motion for dorsiflexion indicated in the literature varies from 12.2 [8] to 18 [9] degrees. [10]
Pronation is a natural movement of the foot that occurs during foot landing while running or walking. Composed of three cardinal plane components: subtalar eversion, ankle dorsiflexion, and forefoot abduction, [1] [2] these three distinct motions of the foot occur simultaneously during the pronation phase. [3]
Dorsiflexion is where the toes are brought closer to the shin. This decreases the angle between the dorsum of the foot and the leg. [28] For example, when walking on the heels the ankle is described as being in dorsiflexion. [27] Similarly, dorsiflexion helps in assuming a deep squat position. [29]
The range of the ankle motion is also significantly greater in the negative heeled shoes, remaining in dorsiflexion longer throughout the stance and swing phases of gait. The increased duration of dorsiflexion leads to lengthening of the gastrocnemius and soleus muscle-tendon units and the length of the moment arm of the Achilles tendon.

Dorsiflexion of the foot is accomplished with the knee extended post surgical repair. Subcutaneous Achilles tendon lengthening is necessary if dorsiflexion is restricted until the foot can be dorsiflexed to 10 degrees.
