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

Who is the ultra firm support from 100% carbon fiber arch supports made for? Performance athletes, people with especially flat feet and those who overpower other insoles. 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. Dash insoles are made to boost your performance in running shoes, hiking boots and other footwear with 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 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.

Carbon insole

Well made strong. Need some more time with them to fully test durability but looks like they should last a very long time.

Sunshine Girl (San Diego, United States)
Excellent Orthotics

I have used these to replace custom orthotics that were actually making me supinate and causing issues in my knees and feet. I have found my knee pain has disappeared and my feet can talk in these at a normal stride which is a blessing.

Tread Labs Low

So far so good!

Ed Surowiec (Phoenix, United States)
Work well in my Ariats.

Got size 12-12.5. Fit great in my size 11D square toe Ariat cowboy boots. I got the lowest arch support and they felt great on day one.

Best insoles I've ever had as an overweight man

I bought these for outdoor work in steep terrain where I'm on my feet for 6-10 hours a day. I'm 6' 280lbs and I've never had insoles better than these they helped a lot. Once I also found compression socks the combo removed pain from long periods of walking or standing. I put them through a lot and they lasted about a year before the carbon fiber heel cracked on the left support. Tread labs easily replaced the pair and I'm buying extra for my other footwear since I love these insoles.
