Frequently asked questions

• Why is a full-foot lift superior to a standard heel wedge?
  Most heel wedges only lift the back of the foot, which forces the arch to collapse and the foot to slide forward. Mesa provides a level, full-foot foundation that maintains natural biomechanics and prevents the "tiptoe" effect. This ensures your entire kinetic chain stays aligned without causing secondary foot fatigue.
• Will Mesa lifts compress or lose height under my body weight?
  No. Unlike foam or gel inserts that compress by 30% or more, Mesa is built around a patent-pending HexCore™ lattice. Engineered from high-density thermoplastic, it is calibrated to hold its precise height under load. Whether you are standing for a 12-hour shift or training in the mountains, your correction remains constant.
• Do I need adhesive or tape to keep the lift from sliding in my shoe?
  No. Mesa utilizes a precision interlocking design where each layer snaps into the next to form a single, rigid unit. The HexCore™ structure provides a natural grip against the interior of your footwear, eliminating the need for messy tapes or adhesives common with vinyl or foam stacks.
• How many layers do I need for my specific leg length discrepancy?
  Mesa is a stackable system that adjusts in 1mm increments, providing a range from 5mm to 20mm. Once you have your number, you simply snap the interlocking layers together to create your custom height.
• Will Mesa lifts fit in sneakers, dress shoes, and work boots?
  Yes. The slim, technical profile is designed to integrate into most closed-toe footwear. Because the system is stackable, you can tailor the height and length (full-foot, three-quarter, or heel-only) to fit the specific volume of your shoe, ensuring your heel stays seated and secure.
• How long do Mesa lifts last compared to drugstore inserts?
  While foam and vinyl lifts typically degrade within months, Mesa is engineered as a durable hardware solution with a lifespan of 5+ years. The materials are non-porous, moisture-resistant, and designed for thousands of miles of use without losing structural integrity.
• Is a 5mm difference really worth addressing?
  Research shows that biomechanical compensation — including pelvic tilt and spinal curvature — begins at just 5mm. While conventional medicine often ignores differences under 20mm, chronic back, hip, and knee pain are frequently linked to these smaller discrepancies. Mesa is built to fill that 5mm to 20mm gap where the impact occurs.
• How do I go about getting an LLD diagnosis?
  The Gold Standard is imaging. A CT scannogram and standing Xray both for leg length study. More information is on the Get Calibrated˚ page.
