Dash improve biomechanics and deliver superior energy return in a super-strong, ultra-lightweight and nearly rigid insole. The 1.25mm thick arch supports are topped with 5mm thick, ventilated top covers.

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 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.

High Arch support magic

I stand all day at my job and these have been a huge improvement for my high arches. Slight issue with the heel sliding sideways just enough to irritate the bottom of my heel. I think I’ll be able to resolve this with some 2 sided 3M tape to get them centered under my heel.

Dash Insoles

I recently purchased the Dash insoles. I run between 30-50 miles/week. I’ve worn an insole for years as the standard shoe insole does not provide enough support. I wear a size 9.5 shoe and ordered the medium 10-10.5 Dash insole l. I did not need to trim the insole. During my first week of running, I observed that the Dash insole was lighter and more supportive than my other purchased insoles. The insoles are quite comfortable and I do feel some energy return with the carbon fiber arch support. Also, I had been having some issues with toe blisters and the open cell foam helped to decrease friction and has resolved those issues. Overall, 5 stars. Very pleased. Thank you, Tread Labs! I’ll be ordering some Dash Top Covers soon!

Suffered with pain while cycling for years and these helped so much!

Anytime I would ride long or hard (or both), I'd have a lot of pain around my middle toe. It was terrible, I would really suffer with the pain and would have to stop to relieve it but only for it to return maybe 10 minutes after I resumed riding. It was really causing me a lot of issues especially during races. I had tried different insoles, cleat wedges, and socks but these have helped the most!

I started using these insoles and could immediately feel more comfort for my entire foot over my other insoles. I then did a 6 hour hard gravel bike race and never had the issue with the pain near my middle toe! I also made sure to start stretching my feet and calves more in addition to using these and I believe the two together have helped cure my pain! I will be ordering another pair for both sets of cycling shoes I own! Thanks!

Love them!

I was surprised to find the rigidness of these carbon fiber insoles to be what I needed to help me stay up throughout the day, what a blessing to live in a time where these exist, thank y’all
