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

For performance athletes, people with especially flat feet and those who overpower other insoles, getting ultra firm arch support is non-negotiable. Dash Thin insoles’ 1.25mm thick, 100% carbon fiber arch supports are a game changer when it comes to improving biomechanics, delivering superior energy return, boosting performance, and minimizing injury risk. Finished off with a 3mm thick, ventilated full length top cover, Dash Thin insoles fit perfectly in cycling shoes, cleats, and other footwear with thin, full length removable inserts.

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 Thin Insoles 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.

Excellent quality, very lightweight

I’ve used the pace insoles for years. The dash is a great option for soccer cleats where weight and thickness make a difference.

Happy Feet

I stand all day on hard concrete floors and have constant foot pain!
Use of the Tread Labs inserts have made a remarkable difference. There are plenty of combinations for a pseudo-custom fit. The return policy is excellent as well!

Best design I have found in 25 years of using arch supports!

For over 25 years I have used Super Feet arch supports in my shoes and boots and I always considered them the best that were available at that time. After my wife purchased a set of DASH insoles I have to acknowledge their superiority! The carbon fiber construction will last indefinitely and hold the shape of the arch. The positioning of the arch was spot-on. The hight was just right with HIGH and the method of holding the position of the insole cushion and the fact you can replace the insole cushion is very well thought out! I would definitely recommend Tread-Labs to anyone serious about finding a no compromise arch support!!

High arches, overpronation

We purchased some Dash Thin High Arch insoles for our son, to help with his overpronation. Not only have they corrected his ankles from turning in, they are also helping to maintain his shoes in quality condition. His prior overpronation caused him to wear out the insides of the shoe soles prematurely.

Hi Kenneth,

Thank you for taking the time to share your feedback.
We're happy to hear the insoles are working out great for your son.
If we can be of any future assistance please email us at

Have a great day,
Tread Labs
