  • 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.

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.

Kyle Oblinger (Baton Rouge, United States)
Ramble insoles

I highly recommend purchasing a few insoles to decide which arch support is right for you. Tread Labs return policy is 90 days which is brilliant and enough time for you to really make sure you have the right ones.

Hi Kyle! Thanks for the support! We want to guarantee our customers take their time to really enjoy their insoles and to find the right fit!

Chris W (Hatboro, United States)
So far so good.

I have tried other inserts before and they worked a little bit, but the difference here is obvious. I can feel how sturdy the product is and I can tell I'm not going to lose arch support in a couple weeks since the material is so rigid. Very pleased.

Hi Chris! We are thrilled the Dash is working out for you! Folks they prefer a very supportive, and rigid insole that do not bend, tend to prefer this style.

AMANDA WHITE (Bruceton Mills, United States)

Does this fit in track spikes?

Hi Amanda! Yes, the Dash insoles are great for cleated footwear. It is very supportive, and rigid insole. The Dash’s carbon fiber arch supports do not bend, providing a pretty aggressive fit and feel. If you have any further questions, please don't hesitate to email us at

A life changer!

I’m a 66 year old female and for years I have had a lot of pelvis and knee problems. I had knee surgery in December for two torn menisci and have had trouble getting over it, even with therapy. I finally discovered via therapy videos that my problem might be made worse by not having arch support, so I researched and tried Tread Lab inserts. They help a LOT! I can’t wait to put on my shoes in the morning to get that good support. I’m back to feeding cattle on our ranch, which requires my climbing in and out of tall cottonseed trailers and also in and out of the pick-up truck bed. I love my Tread Lab inserts! I’m getting my life back, and they are helping.

Dash insoles

Insoles are helping. Should have gotten the extra high arch support instead of the high. Send me a coupon before the price increase and I will try the extra high arch support. Thanks phil lambert
