Sizing and Fit Questions

Here is an easy method to determine your arch height:

1. Fill your tub with a small layer of water.

2. Take two pieces of cardboard or heavy paper and set them on the floor.

3. Step into the tub with one foot to wet the bottom of your foot.

4. Lift up your foot and step onto one cardboard piece. Put your full weight on that one foot.

5. Step off the cardboard and look down.

Determine your arch height. If you see your entire footprint, you have a LOW arch. If you see half of your arch—like the typical "footprint in the sand" image—you have a MEDIUM (normal) arch. If you see a “C” shaped imprint, you have a HIGH arch. If you see just your heel, the ball of your foot and almost no arch at all you have an EXTRA HIGH arch. You can also use this helpful chart as a guide. Repeat the process with the second foot.

The interchangeable top covers on our insoles are designed to be trimmed to fit into your shoes. In nearly all cases, they are wide enough for wide feet.

Possibly, depending on the types of shoes. Some footwear like cycling shoes and ski boots have a very snug fit. If you are close to the lower limit of the size, sizing down for these snug fitting shoes may be beneficial. Tread Labs orthotics are not compatible with shoes that have heels higher than 1".

For women whose feet measure 5-6.5, we offer a low and medium arch height. For women who measure 7-8.5, we offer low, medium and high. For women whose feet measure 9-10.5, we offer low, medium, high and extra high.

Women with a shoe size larger than 10.5 can order a men’s size. Women’s sizing is typically a size and a half bigger than a men’s. For example, a women’s 11 is equivalent to a men’s 9.5. You can also use this chart as a guide.

A men’s 12-13.5 is the largest size we currently offer.

Many people with flat feet benefit from orthotic insoles. Usually flat feet respond best to low or medium arch supports. This article 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 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.

The Stride offers the thickest interchangeable top cover at 4mm. The interchangeable top covers for the Stride Thin and Stride Short are 2mm 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 30-day fit guarantee. Check out our video here.

Yup.

We don't. There are a small number of people that really need custom orthotics, but the vast majority find the semi-custom orthotics that Tread Labs offers are perfect for their needs.

We chose a 100% polyester fabric specifically designed for footbeds. It has very high abrasion resistance, low friction to eliminate hot spots and blisters, and a permanent anti-microbial treatment for stink-free shoes.

Tread Labs insoles are already molded to provide you with a near custom fit. Heating our insoles will damage their supportive structure. In addition, without a trained Pedorthist to help with the molding, many foot problems are simply embedded in heat 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.

Placing a dryer sheet beneath the molded arch support will completely eliminate the sound, and keep your shoes smelling fresh.  We’d be happy to send some sheets your way if needed.

Right now Tread Labs insoles are available online only. If you have a local shop where you would like to be able to try Tread Labs, please email us or ask the shop to feature our brand.

Your Plantar Fascia is the connective tissue that connects your heel to the ball of your foot. 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 at the attachment point at the heel. This is Plantar Fasciitis.
