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.


We offer free shipping via USPS within the US. Transit time is 4-5 business days.

Shipping to Canada is $10 with a transit time of 5-7 business days.

International shipping costs $25 for 1-2 pairs and $40 for 3-5 pairs. All duties, taxes and fees are paid by the customer.

We ship Monday-Friday, excluding holidays.

  • 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.

  • 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.

  • 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.

How Firm Do You Like It?

Just like a mattress, insoles come in different levels of firmness. Choose from firm, extra firm, and ultra firm. Picking the one that's perfect for you is easy with our Find Your Fit Tool.

Dash Insoles Feel Great!!

The Dash Insoles felt a little uncomfortable at first but once my feet got used to them it’s like they weren’t even there! I had an issue with one of the insoles squeaking when I took a step but I adjusted the bottom part of the insole and fixed the problem. Great insole!

Great service and great product

I'm impressed with how easy Tread Labs has made it for me to both purchase and exchange insoles. I am new to the company and didn't know which product, arch height or length would work. I'm getting there now with a higher arch, bigger size (for flexibility) and surprisingly am liking the blue ones best - at least for work. I'm happy with their care most of all and will be ordering more soon.

Hi Sandra,
Thanks so much for giving us a try. We try to make it as easy as possible for you to get the perfect insoles for your feet, so we're glad to hear you were able to get the perfect fit from your insoles. We appreciate you sharing your review!

Excellent product

I have tried many different insoles but none are as comfortable and effective as Dash.
