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.

Dash Insole Kit

Great set of insoles! Been battling plantar fasciitis and these are providing relief, support for healing, and able to get back out running. Much higher quality than my wife’s custom orthotics. Only thing I would do differently is go with the high arch vs extra high arch.

I have had bunions causing pain for some time. After a week of wearing these the pain is gone! Bunions are still there but the support is helping to keep them from becoming painful through the day! Absolutely love them! Cant wait to get more so I can stop switching them between all my shoes!

Stiff and versatile

The carbon shell is very well made and stiff. Having multiple insole foam options are definitely helpful

Manishh Gajiwala (Milpitas, United States)

Works great. Stop my arch pain.

Hi Manishh. Happy to hear the insoles are working out.

Grant Swanson (Manassas, United States)
Pretty good

Essentially comparable to Superfeet. I like the reusable My inserts. My only complaint is the inseert is a slick material and creates friction and i get a blister

Hi Grant! Thank you for your feedback. We will definitely relay this to our team and we hope to your feet feels better.
