Using Run 619 Flat Insoles for Leg Length Discrepancies

Leg length discrepancies, even minor ones, can create long-term discomfort in your hips, knees, and back. While traditional heel lifts are a common solution, they can throw off your alignment by raising only the heel. At Run 619, we’ve heard from many customers who have found our flat, zero-drop insoles to be a simple and effective alternative.

A Different Approach to Correction
Run 619 insoles weren’t designed specifically to correct leg length discrepancies, but their design makes them ideal for it. Because our insoles are completely flat (zero drop) and the same thickness from heel to toe, they provide a subtle, full-foot lift without introducing unwanted angles or pressure points.

How It Works
Many customers with mild discrepancies — usually 3mm to 6mm — simply insert one Run 619 insole into the shorter-side shoe. The result is a slight lift that helps even out gait and reduce strain, especially during walking or standing for long periods.

Why Not a Heel Lift?
Heel lifts can create an uneven platform in your shoe, causing your foot to slope forward unnaturally. Over time, this can lead to toe jamming, balance issues, or more stress on your joints. A flat insole provides a more natural and consistent feel from heel to toe.

Available Thickness Options
Run 619 insoles come in three thicknesses:

• 3mm: Minimal lift, best for subtle adjustments

• 4.5mm: A balanced middle ground

• 6mm: Ideal for more noticeable discrepancies

Tips for Best Fit
For the best results, we recommend measuring the length of your existing insole and matching it to our sizing chart. If you're between sizes or using just one insole, sizing up and trimming to fit is a safe bet.

Final Note
While our insoles weren’t designed specifically as a medical device, we’re constantly hearing from customers who use them successfully for leg length discrepancies. As always, consult a medical professional if you’re unsure about the severity of your imbalance or how best to address it.
