Instep vs. Arch — What's the Difference?
By Fiza Rafique & Urooj Arif — Updated on March 24, 2024
The instep is the upper part of the foot between the toes and the ankle, notable for its rise, while the arch refers specifically to the curved underside of the foot that does not touch the ground.

Key Differences
The instep and the arch of the foot are distinct but related parts of human anatomy, each serving specific functions in foot mechanics and overall posture. The instep is often visible when looking at the foot from the side and is associated with the foot's dorsal (top) aspect. It plays a key role in determining the type of footwear that fits comfortably, as a high instep may require shoes with more room or adjustable closures. On the other hand, the arch, located on the foot's plantar (bottom) side, is crucial for absorbing shock and supporting the body's weight during standing, walking, and running.
Footwear design and fit considerations differ significantly between the instep and the arch. For individuals with a high instep, finding shoes that accommodate the foot's higher rise without causing discomfort is essential. Conversely, shoes designed to support the arch can help prevent conditions such as plantar fasciitis and flat feet, emphasizing the need for supportive insoles or specific shoe designs that cater to low or high arches.
The instep and the arch function together to facilitate efficient movement. The instep's shape can influence how pressure is distributed across the foot, while the arch's flexibility and structure are key to shock absorption and propulsion during the gait cycle. A well-defined arch helps distribute body weight across the feet and legs, whereas the instep's contour can affect the fit and comfort of footwear and the distribution of lace pressure in tied shoes.
From an anatomical perspective, the instep comprises the bones and soft tissues on the foot's dorsal surface, including the metatarsals and the extensor tendons. The arch, however, is formed by the tarsal and metatarsal bones, supported by ligaments and tendons, including the plantar fascia, which plays a significant role in maintaining the arch's shape and functionality.
When addressing foot health and footwear choices, both the instep and the arch must be considered. Proper support for the arch can alleviate pain and prevent injuries, while accommodating the instep's height ensures comfort and prevents constriction. Orthotics and specially designed footwear can address issues related to both the instep and arch, underscoring the interconnectedness of these foot parts in achieving overall foot health and comfort.
