4 Inch Shoe Lift — Custom Build-Up Bonded Into Your Own Shoes

A 4 inch shoe lift (about 10 cm) is the largest standard height we build, and we go beyond it — 5″ and 6″ extended lifts are available at $20 per additional inch. At this size the lift is an orthopedic device first and a shoe second, so the build is all about stability: a wide heel base, a full rocker profile, a honeycomb core to hold the weight down, and rigid material throughout.

Height band: 3 1/8″ – 4″ (7.9–10.2 cm). Price: from $164.99 per pair, any shoe type, free shipping both ways. Turnaround: work completed in 1–3 business days once your shoes arrive.

• A measured leg length difference of roughly 3 1/8″ to 4″, or larger.
• Patients with significant congenital shortening, post-polio or post-trauma differences, or those preparing for limb-lengthening surgery.
• People correcting in stages who have reached the top of the range.
• Anyone currently wearing a heavy custom shoe or a home-built block who wants a lighter, purpose-built lift in a normal shoe.

This page is general guidance, not medical advice. For any difference over about 1/2″, or if you have pain, confirm the lift height with your doctor or physical therapist first. Our page on signs you need a shoe lift includes a tool to find a specialist near you.

The sole is split and a full-length layer is bonded and shaped to the final height. The heel base is widened well beyond the shoe outline for lateral stability; the forefoot is tapered into a full rocker so the step rolls; the outer surface is finished to match the sole. Extended lifts above 4″ are built the same way with a proportionally wider base.

At 4″ and above we build with the honeycomb core and rigid material as standard recommendations — the core keeps weight manageable and the rigid material stops any flex or twist. Send a boot or a high-top sneaker with a wide outsole and a firm heel counter; we will tell you honestly if a shoe is not suitable before we start.
