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, soccer 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.

Dash thin insoles

The insoles are great- a bit time to get use to but really help you run with the best form

Rae Lynne Kinler (Stamford, United States)
Favorite so far!

I love the thin insoles. I have the short ones but feel they don’t stay put in the carbon plated shoes that don’t have removable insoles, so I tried the thin version and they are awesome. All the stability without the bulk, and no added pressure in the toe box.

Seriously helped my tarsal tunnel pain

I play a *LOT* of competitive soccer. I’ve always struggled with rolled ankles/sprained ankles. Recently I developed tarsal tunnel syndrome due to repeated sprains and inflammation of my ligaments. It was extremely painful. These insoles helped to correct my supination and high arches, alleviate the pain and enabled me to get back to playing!

Hi Dan! We're glad the insoles are helping to alleviate the pain. Keep kicking for the goal.

Helped with hip and knee pain

Added to cycling shoes. Get more stable on the bike and less pain. Highly recommend

Hi Kevin! Folks that are cyclist tend to prefer this style and you picked the right one.

Great product & customer service

I put more pressure on the outside of my foot and this started to cause some issues during longer cycling sessions. So I called Tread Labs and asked for a recommendation. The really nice guy on the phone went through my options in detail and gave me two choices that would work. I purchased the Dash thin insoles. I like them but I think that I have a problem that many reviewers have—two different arch heights. So one foot feels great and the other one, well, I’m waiting to see if it settles in or if I will have to buy a second set in a lower height. Even though two sets would be expensive, once I get everything right, I think they’ll be the last cycling insoles I’ll have to buy.

Hi Dawn! Thank you for the wonderful feedback.
