Foot Pain and Arch Issues Explained:

Common Conditions We Treat (and Why They Happen)

The foot is an architectural marvel—a structure of 26 bones, 33 joints, and more than 100 muscles, tendons, and ligaments that work together to absorb shock, adapt to uneven terrain, and propel the body forward with every step. When any part of this system is compromised—by structural issues, overuse, poor footwear, or muscular imbalance—the effects can be felt not just in the foot itself, but throughout the entire lower extremity and even into the low back. Foot pain is rarely just a foot problem.

Flat Feet (Overpronation)

Flat feet occur when the medial arch of the foot collapses, causing the foot to roll inward excessively during the gait cycle. This overpronation increases stress on the plantar fascia, the posterior tibialis tendon, the Achilles tendon, and the knee. While some degree of pronation is normal and necessary for shock absorption, excessive and prolonged pronation without adequate muscular support creates cumulative strain across the entire lower kinetic chain. Flat feet can be structural (present from birth) or functional (developed over time due to muscle weakness or footwear).

High Arches (Supination / Underpronation)

A foot with an excessively high arch has the opposite problem: it is too rigid and doesn’t pronate enough to absorb ground reaction forces. Instead, load is concentrated on the heel and the ball of the foot, increasing the risk of stress fractures, metatarsalgia, plantar fasciitis, and lateral ankle instability. High arches are often accompanied by tight calf muscles and a tendency to walk or run on the outside of the foot, placing excess demand on the peroneal tendons.

Metatarsalgia (Ball of Foot Pain)

Metatarsalgia refers to pain and inflammation in the ball of the foot, where the metatarsal bones meet the toes. It typically develops from prolonged pressure or repetitive impact—common in runners, people who wear high heels, or those with structural foot issues that shift weight forward onto the metatarsal heads. It presents as a burning, aching, or sharp pain under the front of the foot that worsens with walking or standing.

Morton’s Neuroma

A neuroma is a thickening of the nerve tissue between the metatarsal bones, most commonly between the third and fourth toes. The compressed or irritated nerve produces burning, tingling, or numbness in the toes, and patients often describe the sensation of walking on a pebble or a bunched-up sock. Tight footwear, high heels, and repetitive compression of the forefoot are common contributors.

Posterior Tibialis Tendon Dysfunction

The posterior tibialis muscle plays a central role in supporting the arch during the gait cycle. When this tendon becomes overloaded—through overuse, sudden increases in activity, or structural flat-footedness—it can progress from tendonitis to partial tearing and eventually a painful acquired flat foot deformity. This condition is commonly underdiagnosed and is one of the more serious causes of inner ankle and arch pain in adults.

Footwear and Surface as Contributing Factors

The shoes we wear and the surfaces we stand on are among the most significant and modifiable contributors to foot pain. Shoes with insufficient support, a narrow toe box, or excessive heel elevation alter the biomechanics of the entire foot and lower leg. Transitioning too quickly to minimalist footwear, spending long hours on hard floors without adequate cushioning, or wearing shoes well past their functional lifespan all increase injury risk significantly.

The Bottom Line

Foot pain is one of the most undertreated conditions in musculoskeletal care—often managed with orthotics or footwear changes alone, without ever addressing the underlying tissue restrictions, joint mobility deficits, or muscle imbalances that are driving the problem. A comprehensive approach that combines manual therapy to restore proper joint mechanics, soft tissue work to release the structures under excessive tension, and corrective exercise to rebuild foot and hip strength produces far better long-term outcomes than passive support alone.
