Valentine’s Day Gift Ideas For Outdoorsy Couples (His & Hers)
Five free ways to say I love you outdoors, plus practical his and hers gear picks
Most running shoes talk a big game. Max stack. Pebax plate. Foam du jour. But once you pop the insole out, it’s usually the same story; thin, generic, and forgettable.
That’s where Tread Labs is making their mark.
Their new Run Insole, launched November 5, 2025, is built from the ground up to solve the one part of your running shoe that doesn’t always deliver: the actual interface between foot and midsole.
It’s a high-performance foundation made with nitrogen-infused supercritical foam, clinical-grade arch support, and size-specific fit architecture that eliminates slippage, maximizes energy return, and minimizes fatigue.
The technology
At the core of the Run Insole is a combination of materials rarely (if ever) seen in aftermarket insoles:
- Nitrogen-infused foam — super lightweight and very responsive, this is the same high-performance compound you’d find in elite racing midsoles, just repurposed for your entire rotation.
- Recyclable polypropylene arch supports, available in four heights and backed by the brand’s Million Mile Guarantee.
- Heel plug engineering, including a 6mm PU pad and calcaneal drop zone to absorb shock where you land hardest.
- A sweat-wicking PURE® antimicrobial top cover for comfort that stays fresh run after run.
All of that’s packed into a 5mm profile, so the insoles fit seamlessly into most running shoes without creating extra bulk or affecting the shoe’s intended geometry.
Sizing options for all foot shapes
The Run Insole doesn’t guess at your arch shape.
It meets you where you are, with four arch options (low, medium, high, and extra high) and eleven sizes for both men and women.
That means no trimming, no folding, and no compromises.
Once you find your fit, the experience is simple: slide them in, lace up, and go.
The difference should feel immediate, especially for runners who’ve struggled with arch collapse, hot spots, or instability during long runs.
And when the top cover wears down? You don’t throw them out. Just swap it for a fresh one and keep going. Smart for your feet, and smarter for the planet.
Designed by the guy who built Chaco
Tread Labs is the latest chapter in Mark Paigen’s footwear legacy.
As the original founder of Chaco, Paigen knows a thing or two about biomechanics, arch support, and how to make gear that lasts.
With Tread Labs, he’s turning that expertise toward performance running, and starting with the one piece of gear many overlook.
Final thoughts
Runners often chase the next best shoe but your stride starts at the foundation.
With the Run Insole, Tread Labs has flipped the insole category on its head, blending elite-level materials with customizable fit and long-term sustainability.
Whether you’re logging marathon miles or recovering from overuse niggles, this might be an upgrade worth trying.
