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.
NOTICE: The thin, firm nature of carbon fiber may damage the lining in some footwear.
Million Mile Guarantee
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.

One size does not fit all.
Pants 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.
Dash Insoles have been granted the American Podiatric Medical Association's Seal of Acceptance.
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.
