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.


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.

A great learning experience from a great product

Let me say I've been running for about 13 years, beginning in my early 30s. It's taken some time to find which shoes (neutral, stability, stack height, heel drop, etc) work for my feet and body. Even sophisticated shoe store measurements did not help.

I tried Tread Labs medium arch insoles with the metatarsal pads, since I have Morton's neuroma on my left foot. These performed wonderfully, but I started to wonder if I indeed needed high arch support.

I've done the wet paper bag experiment many times and can never get an accurate reading, so I've always flown blind on that and just assumed I had a medium arch. I purchased this pair of Dash insoles with high arches and it has been heaven to run in them!

The higher arch supply has definitely suited my feet more, and my mileage continues to climb as 2022 gets started. Now I just have to find a magical method of procuring 3 or 4 more pairs for all my running shoes!

Hi Steven,
Wow - we're so glad you tried the high arch and got a great fit! As you know, matching your insoles to the contours of your arches makes all the difference. All the best for big pain-free miles in 2022!

Great ultra-low profile support for cleats

Been looking for an ultra-low profile insole for my soccer cleats, since they're already pretty tight with the stock insoles. I went with the Dash Insoles with thin covers and they work beautifully. My feet are much less sore after playing soccer! 10/10 would recommend.

Hey David,
It's so awesome to hear the Dash Thin insoles are a great fit in your soccer cleats and are keeping your feet in good health during and after your time on the pitch. Thanks so much for giving us a try!

Pain free pedaling

I ride a pedicab and was suffering with hot spots and would miss days of work from the pain. Now with my dash thin insoles my feet feel so much better. I wish I had known about these years ago. I absolutely recommend them.

Don H (Denver, United States)
Comfortable for high arches

It is difficult to find off-the-shelf insoles for my high arches. Custom insoles are usually too bulky for the kind of footwear I wear. I usually just deal with the pain in the front and back of my feet without the necessary arch support. So I was glad to find these Dash Thin Insoles online. I have only used them a couple times for hiking so far, but I do notice the high arch support and my feet feel more comfortable and less fatigued overall.
