The deep heel cup support in a Modulign orthotic is a critical feature that provides enhanced stability and alignment for the foot. The heel cup is the part of the orthotic that cradles the heel, holding it in a firm and supportive position. It extends slightly higher than the rest of the orthotic to encompass and stabilize the heel, preventing excessive movement and providing essential control during weight-bearing activities. This is the only orthotic with such a deep heel cup that you can fit yourself.

The deep heel cup support serves several important functions:

1. Stability: By enclosing the heel, the deep cup helps stabilize the rearfoot and prevents it from rolling excessively inward (pronation) or outward (supination) during gait. This stability is crucial for maintaining proper foot alignment and reducing the risk of injuries and strain.
2. Arch Support: The deep heel cup works in conjunction with the arch support of the orthotic to promote proper foot mechanics. It helps distribute pressure evenly across the foot, which is especially beneficial for individuals with flat feet or fallen arches.
3. Shock Absorption: The deep cup design helps absorb and disperse impact forces that occur during walking, running, or other weight-bearing activities. This can reduce the stress on the heel and the entire foot, potentially alleviating discomfort or pain associated with certain conditions.
4. Comfort: The deep heel cup is typically lined with a cushioning material, which enhances overall comfort for the wearer. It can provide a snug, supportive feel that helps reduce fatigue during prolonged standing or walking.
5. Prevents Overpronation: Overpronation (excessive inward rolling of the foot) is a common issue that can lead to various foot and lower extremity problems. The deep heel cup support helps counteract overpronation by providing corrective support, thus promoting more natural foot movement.

Modulign orthotics are orthotics you can fit yourself and you can adjust the depth and contour of the heel cup so that it can be tailored to an individual's specific foot shape and needs. This customization ensures that the orthotic fits properly and provides optimal support and functionality.
