A new era of performance starts underfoot.
The all-new Run Insole is built from the ground up with nitrogen-infused supercritical foam that propels every stride forward — our lightest, most responsive design yet. A precision heel plug absorbs shock on impact, while a reengineered arch and top cover evenly distribute weight for smoother transitions and lasting comfort. The result: less fatigue, more power, and the first step in Tread Labs’ next-generation insole line.

What Makes Run Insoles Better
-
One size does not fit all.
Run insoles come in four arch heights – low, medium, high, or extra high – so you can get the perfect fit for your feet.
-
Like new, on demand.
Tread Labs insoles are made with a 2-part system: an arch support and a replaceable top cover. Easily replace the top cover to make your insoles like new again.
-
Built on breakthrough foam.
Nitrogen-infused supercritical foam delivers high-rebound cushioning that outlasts ordinary materials — comfort that keeps performing.
-
APMA Approved
Run Insoles have been granted the American Podiatric Medical Association's Seal of Acceptance.
-
Together, They Rip.
Shoes protect. The Run Insole powers. Together, they deliver stride-correcting alignment, explosive energy return, and comfort that doesn’t quit. Less wasted motion. Less fatigue. More speed, more endurance, more PRs. This is running unlocked.
-
The Fix Your Shoes Missed.
Running shoes come and go. The Run Insole stays. Built with recyclable polypropylene, nitrogen-infused supercritical foam, and our Million Mile Guarantee, it’s the upgrade that stays with you run after run, changing how you train, race, and recover. One upgrade. Infinite miles.
-
Master Your Stride. Or Get Left.
Every stride starts with your foundation. The Run Insole stabilizes your arch, reduces joint stress, and improves running mechanics. Stronger form means more efficiency, fewer injuries, and faster recovery. Better form. Stronger runs. Fewer setbacks.
Fit It. Forget It. Fly.
No two runners are the same and neither are their arches. With four arch heights and 11 size options, the Run Insole dials in a custom fit your shoes can’t. The result: more stability, less slippage, and a stride that feels built just for you.
Engineered Where It Matters Most.
Impact begins at the heel — so we rebuilt it. The Run Insole’s precision heel plug absorbs shock, improves alignment, and helps you stay powerful through every stride. It’s a small detail with big results.
Stronger Stride. Fewer Setbacks.
Every misaligned step steals energy and increases risk. The Run Insole stabilizes from the ground up: aligning joints, improving form, and protecting against the injuries that cut training short. Run longer. Finish faster. Recover Stronger.
