Can Diabetes Change the Shape of Your Feet?

Diabetes is often associated with numbness, wounds, and slow healing, but it can also contribute to structural changes in the feet. These changes may affect balance, shoe fit, and how pressure is distributed while walking. During Diabetes Awareness Month, Goldsmith Podiatry in Manhattan explains why changes in foot shape should not be overlooked.

How Can Nerve Damage Affect Foot Structure?

Diabetic peripheral neuropathy can reduce sensation in the feet, but sensory nerves are not the only nerves that may be affected. Motor nerve damage can weaken the small muscles that help stabilize the toes and arches.

As certain muscles weaken, others may pull more strongly. Over time, this imbalance can contribute to hammertoes, claw toes, prominent joints, or changes in the arch. These deformities can create new pressure points inside shoes, increasing the risk of corns, calluses, blisters, and wounds.

Loss of sensation may prevent a person from feeling that a shoe is rubbing or that one area is absorbing too much pressure.

What Is Charcot Foot?

Charcot foot is a serious diabetes-related complication involving weakened bones, joints, and soft tissues. Minor trauma may go unnoticed because of neuropathy. Continued walking can then cause bones or joints to fracture, shift, or collapse.

Early signs may include:

●      Swelling in one foot

●      Redness or warmth

●      A noticeable difference in temperature between the feet

●      Changes in the arch or overall foot shape

●      Little pain despite visible swelling

Charcot foot requires prompt medical attention. Continuing to bear weight on the affected foot may lead to severe deformity and additional complications.

What Changes Should You Watch For?

Examine your feet daily and notice whether your toes, arches, or pressure points look different. Check for redness, calluses, blisters, swelling, and areas where shoes leave marks. A previously comfortable pair becoming tight may also signal a change.

Regular diabetic foot care can identify nerve changes, circulation concerns, skin damage, and structural problems before they progress. Never trim thick calluses or use medicated corn removers without professional guidance. Review these additional diabetic foot-care do’s and don’ts.

When Should You Schedule an Evaluation?

Contact a podiatrist promptly if one foot becomes warm, red, swollen, or suddenly changes shape. Even painless changes require attention when neuropathy is present.

The podiatrists at Goldsmith Podiatry can examine your feet, assess pressure patterns, and recommend protective footwear, custom orthotics, wound care, or other treatment. Monitoring structural changes is an important part of protecting long-term mobility. Call (212) 877-1002 to schedule an evaluation with Dr. Howard Goldsmith, Dr. Rosanna Troia, or Dr. Kristina T.
