1. Step onto a piece of heavy paper or cardboard with your wet foot. Left foot then right.
2. Review your footprints and compare them to the footprints on this helpful chart to determine your arch height.

To replace your top covers, separate the old covers from the arch support at the hook and loop connection points. Align your new top cover on the connection points and press together to attach. Watch this quick video for a visual demonstration.

Tread Labs unique 2-part insole system features a molded arch support and interchangeable top cover. Insoles are available with 1 of 3 different top covers (regular, short or thin) to accommodate shoes with removable inserts, shoes without removable inserts, and low-volume footwear with thin, removable inserts. Top covers can be purchased separately to make 1 pair of arch supports fit perfectly in different types of shoes.

Yes. Tread Labs insoles should replace the factory insert in your footwear. If your shoes do not have removable inserts, you'll want our short insoles.

Our Insoles go up to size 47

If you would like to buy Tread Labs insoles in bigger sizes, please let us know. The more demand we have, the faster we will increase our offering.

Many people with flat feet benefit from orthotic insoles. Usually, flat feet respond best to low or medium arch supports. This article about arch support insoles explains the details. Try Tread Labs insoles and see what they can do for your comfort. If you're not completely satisfied, send your insoles back within 90 days for an exchange or full refund. We'll cover domestic (US) shipping.

We do not sell mixed arch heights. For a set of mixed heights, you’ll need to purchase 2 separate pairs. Or, consider purchasing a pair of insoles with the lower of the two arch heights and see how they feel.

Supportive - Your foot should feel constant contact through all parts of your arch. There should be no uncomfortable pressure points.

Comfortable - Initially, a supportive orthotic may feel aggressive. After a few days, it should feel like it has always been there; not having it in will feel hollow and unsupportive.

Resilient - Your arch is designed like a spring to absorb the impact of walking. Orthotics should bolster your foot's natural shock-absorbing structure.

Our regular, full length, top covers are 5mm thick. Thin and short top covers are 3mm thick.

In some cases yes. This is because shoe sizes vary by manufacturer.

If trimming is necessary, remove the stock insole and use it as a cutting guide for your new insoles. Be conservative. Trimmed insoles are still covered by our 90-day fit guarantee.

Yup. Tread Labs molded arch supports are covered by our Million Mile Guarantee. If they ever crack or lose shape, we'll send you a new pair. No questions asked.

We use a 100% recycled polyester fabric specifically designed for footbeds. It has high abrasion resistance and low friction, to eliminate hot spots and blisters. In addition, it is infused with a permanent anti-microbial treatment for stink-free shoes.

Tread Labs insoles are available in 4 arch heights to provide you with a customized fit. Heating our insoles will damage their supportive structure. In addition, without a trained Pedorthist to help with the molding, foot problems can be worsened with DIY molded orthotics.

The molded arch supports are guaranteed. Forever. The interchangeable top covers should last a year or so, depending on usage. They can easily be replaced without breaking the bank.

If you remove your Interchangeable Top Covers from the molded arch supports, you can hand wash and air dry them. However, if they are in really rough shape, you can always order a new set of top covers.

If you encounter this problem, placing a dryer sheet beneath the molded arch support will completely eliminate the sound, and keep your shoes smelling fresh.

The arch height on our sandals compares most closely to the medium arch height on Tread Labs Insoles.

If you wear a half size or are in between sizes, please size up to the next larger size.

Tread Labs sandals have an accommodating fit. We encourage customers with wide feet to give them a try. They can be returned in new condition for a full refund.

They have incredible arch support for all day comfort.

They feature a luxurious microfiber footbed that keeps feet feeling cool and dry.

They offer a unique combination of light weight and durability.

Absolutely! All Tread Labs sandals are made with water-friendly materials.

The easiest way to clean your Tread Labs sandals is to put them in the washing machine with your dark clothes. Do not put them in the dryer.

Tread Labs sandals are not designed specifically for running and hiking. Experiment with your new sandals to see what they can do.

Your foot will rest on a microfiber footbed that is made of polyester with an anti-microbial treatment. The straps are made from 100% recycled polyester.

Hammertoes and bunions are easily accommodated with Tread Labs sandals. People with plantar fasciitis may find Tread Labs sandals especially comfortable because of the high level of arch support in the contoured footbed.

Easy, Just throw them in the wash with your dark clothes and air dry them from time to time to keep them fresh.

The sandal straps will feel snug initially and will loosen up about 10%. The straps are soft and accomodating from the start. If you are new to wearing sandals that have a strap between your toes, starting with a few hours a day will help your feet get used to the new feeling.

Your Plantar Fascia is the connective tissue that connects your heel to your toes. If you look at the bottom of your foot and pull back your big toe, you will see a band under the skin that goes from the heel to the ball. This is the Plantar Fascia. When it gets stressed from over pronation, inflammation and pain develops, usually where the plantar fasciia attaches to the heel. This is Plantar Fasciitis.

Pronation is the inward rolling of the foot as a step is taken. Over pronation occurs when the foot rolls too far inward before you push off to move forward. When this inward rolling motion goes too far, the alignment of the foot is compromised and there is a loss of efficiency in every step you take. Negative effects of overpronation include arch collapse, plantar fasciitis, inefficiency and pain in your feet, knees, hips and back.

Shin splints (tibial stress syndrome) occur when the muscles and tendons surrounding the tibia (long bone between knee and heel) become inflamed due to repetitive stress. The painful condition is common in athletes, runners, dancers, and anyone who spends a lot of time walking or running on hard surfaces.

Runner’s knee (Pattellofemoral Pain Syndrome, PFPS) is one of the most common running injuries. Symptoms include a dull aching pain at and behind the kneecap, which often becomes more intense after a period of rest. Pain experienced by this common overuse injury can be magnified by walking up and down steps and hills or on uneven surfaces.
