Leg Length Discrepancy: Understanding the Difference
Leg length discrepancy means a difference in the length of the legs. Small differences may cause no problems; the effect varies with the individual and the size and cause of the difference.
Why Is Assessment Important?
An assessment considers leg measurements, movement, and symptoms. A clinician may use a physical examination and, when needed, imaging to understand the difference.
Not every difference needs treatment. Decisions depend on factors such as symptoms, age, and how someone walks, rather than foot shape alone.

Insoles, Lifts, and Individual Advice
A clinician may recommend a shoe lift for certain measured leg-length differences. The amount of lift and how it is fitted require individual assessment; avoid choosing a correction height yourself.
Insole 3D designs personalized insoles from individual foot measurements. These measurements do not establish leg length discrepancy or prescribe a lift. Any need to compensate for unequal leg lengths should be assessed separately by a qualified professional.
Explore Personalized Insoles
Explore our measurement-based insole design and discuss any leg-length needs with your clinician before purchasing.
Seek assessment for a persistent limp, discomfort, or difficulty walking. Do not assume a standard or personalized insole provides the specific lift or treatment you need.
