Heel cracks

From a podiatry perspective, a pronounced heel crack on one side can be an early indicator of a limb length discrepancy (LLD). It often appears alongside back pain or may contribute to future discomfort in the spine, hips, or shoulders.

When one limb is shorter, the body naturally compensates. These compensations can show up as:

• Excessive pronation on one side

• Knee hyperextension or medial/lateral deviation

• Pelvic or shoulder drop

• Tightness in the gluteal or hamstring muscles on one side, with relative weakness on the opposite side

• Heavier landing on the shorter limb, which increases mechanical stress and can contribute to deeper heel fissures on that side

Because the shorter limb often absorbs more impact, the skin on that heel may dry, split, or crack more severely.

The good news is that these issues are modifiable. Management typically includes:

• Heel raises or lifts to help balance limb length

• Targeted strengthening for weak muscle groups

• Stretching programs for tight structures

• Gait retraining when needed

Bilateral heel cracks (cracks in both heels)
are often related to dry, thickened skin, prolonged standing, or improper footwear. They can also be associated with psoriasis, eczema, vitamin D deficiency, thyroid disorders, and metabolic issues like diabetes. Obesity, cold weather, and dehydration increase skin stress on both heels. Mechanical overload from hard surfaces or reduced heel‑pad elasticity can worsen fissuring. Persistent or painful cracking should be assessed by a healthcare professional to rule out underlying dermatologic or systemic causes.
