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.

Wet Foot Test
Quickly and easily find your arch height with this simple test.
What Do High Arches Mean?
People with high arches can often experience foot pain because of the extra stress high arches put on your metatarsal bones. The stress ends up shifting your weight to the ball of your foot.
What Are The Best Insoles for High Arches?
What Do Flat Feet Mean?
Many people with flat feet don't experience any difficulties, but some suffer from pain in the heel or arch (plantar fasciitis), swelling along the inside of the ankles, and knee and hip problems.Rigid vs. Flexible Flat Feet
If your wet footprint indicates you have flat feet or low arches, you'll need to determine if you have rigid flat feet or flexible flat feet because it will change the arch height your feet need for maximum comfort and support. To figure out which type of flat feet you have:
- Sit with one leg over the opposite knee. Look at where your arch should be. If your foot looks more arched than your wet test footprint, you have flexible feet. This means your low arches are brought on by weight-bearing and a medium arch insole will work best for you.
- Stand on tip toes. Have a friend look at where your arch should be. Like the example above, if your arches show themselves, your feet are flexible.
- If an arch doesn't appear in either of the tests, you have rigid, low arches and should choose an insole with a low arch. A higher arch support will probably be very uncomfortable on your arch and feel like you have a golf ball in your shoe.
People with flat feet often ask if they should get insoles for high or extra high arches to try and "fix" their flat feet. While low arches aren't anything that need to be fixed, the do still need to be properly supported.
Using a high or extra high arch on low arches could cause discomfort, and the feeling like something is digging into your arch. A low or medium arch (depending on the flexibility of your foot) is the best place to start.
What Are The Best Insoles For Flat Feet?
The best insoles for flat feet support your arch and stabilize your heel, preventing overpronation. Typically, the best insoles for flat feet will offer a low, but supportive arch. Finding one that matches the contours of your foot is key.
While soft, cushioned insoles might seem like the best choice, what your feet really need is structural support. All of Tread Labs semi-custom insoles come in four arch heights to accommodate arch heights from low to extra high.

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.

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.
