Up your game by optimizing your biomechanics with ultra-firm support.

Athletes who want to boost their performance, people with especially flat feet, and those who overpower most insoles all have one thing in common. They need ultra firm support. Dash Insole Kit has you covered…in every shoe. The super thin, ultra lightweight, nearly rigid 100% carbon fiber arch supports improve biomechanics and stability while decreasing injury risk. Dash Insole Kit includes 1 pair of ultra firm arch supports and 3 styles of swappable top covers – 5mm thick full length, 3mm thick full length, and 3mm thick short – for a perfect fit in all your low-heeled footwear.

Million Mile Guarantee

Tread Labs molded arch supports are unconditionally guaranteed. Forever.

If they ever crack or lose their shape, we’ll send you a new pair, no questions asked. From your first mile to your millionth, your satisfaction is our priority.


Before adding Dash Insole Kit to your shoes, remove the factory inserts. While adjusting to your insoles, you may feel firm support along your arch, but after a week or so, you’ll probably forget you’re wearing them. Give yourself time to get used to the additional support. You’ll be glad you did.

  • Arch support insoles with carbon fiber

    One size does not fit all.

    Pant's aren't one size fits all. Insoles shouldn't be either. Dash insoles come in four arch heights – low, medium, high, and extra high – so you can get the perfect fit for your feet.

  • Dash carbon fiber orthotic insoles for rigid arch support

    Like new, on demand.

    Tread Labs insoles are made with a 2-part system: a molded arch support and a replaceable top cover. Easily replace the top cover to make your insoles like new again.

  • Dash Carbon Fiber Insoles for cycling shoes

    Fresher feet with every step.

    Dash top covers are resilient, long-lasting, open-cell polyurethane foam topped with 100% recycled polyester fabric that's PURE antimicrobial treated to keep feet feeling fresh all day.

Up Your Game

When it comes to competing, you’re not going for second place. The right gear is your performance enhancer on the field or in the saddle. Carbon fiber makes Dash insoles light, low-profile and nearly rigid, lengthening your stride and improving your alignment.

You'll be more efficient with super-thin, lightweight arch support in your sport shoes. That's one for the win column.

No Risk, High Reward

Getting used to firm support can take time. That's why our insoles are covered by a 90-Day Fit Guarantee. Once they arrive, wear them for up to 90 days. Make sure they fit like a glove.

Need a higher or lower arch? Exchange them. Just not your cup of tea? That's okay. Send them back for a refund. We'll even pay return shipping (in the US). It doesn't get less risky than that.

G Mobley (Apex, United States)
Awesome alternative to my custom orthos

I have had PF for 30 years and need custom orthotics to relieve / eliminate that heel pain. In some instances, Rx orthotics are too thick to work in some boots and shoes. I've leaned in the past 2 months that Tread Lab's products, once you find the proper sizing and arch height, work SUPER well in shoes and boots which are unable accommodate my custom orthos. Having my foot molds at home has helped narrow the arch height while my existing custom orthos have helped for the stiffness comparisons.
Highly recommended for any arch support.

Addendum: My better 1/2 and son are now TL customers too! Both wear/need custom orthos, both have extremely HIGH arch's. Both tried Tread Labs over the holidays and I'll be ordering more soon. Thank You for making such a great product! G Mobley

Help with Plantar Fasciitis

Three weeks into daily use of my insoles and I'm noticing a significant decrease in my heel and arch pain. They also fit nicely into many kinds of shoes. Would recommend to others!

Total Game Changer

I have no arch. When I say that, I don’t mean that I have a low arch or little arch. I have absolutely none.
These have changed everything. I fit in my ski boots so much better. My ankles and top of the foot don’t hurt after running. My feet make shoes look normal and not all wonky now. And they are comfortable.
Could not recommend more highly.

Best insoles to date.

After using a few various insoles for plantar fasciitis. These not only cradle and support my arch. They are slimmer and fit in just about every pair of shoes. I got the shearling lined pads to pair with my ugg boots and they fit perfectly as if they were factory. Highly recommended
