Which condition may require the use of a foot orthosis to correct alignment?

Plantar fasciitis often benefits from the use of foot orthoses to correct alignment and provide support to the arch of the foot. This condition involves inflammation of the plantar fascia, which is a thick band of tissue that runs across the bottom of the foot, connecting the heel bone to the toes. The use of orthoses can help redistribute pressure on the foot, provide cushioning, and improve overall biomechanics during walking or standing, which can alleviate strain on the plantar fascia.

The alignment can play a crucial role in the development and persistence of plantar fasciitis; therefore, an orthosis that addresses overpronation or underpronation can be particularly useful in managing this condition. By correcting imbalances in the foot's alignment, foot orthoses help to decrease pain and improve function, allowing the tissues to heal more effectively.

For the other conditions, while orthotic intervention may also be considered, the primary need for orthotic correction is most commonly associated with plantar fasciitis due to its direct impact on foot alignment and function.
