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 foam top covers on our insoles are designed to be trimmed to fit into your shoes. In most cases, they are wide enough for wide feet.

Possibly, depending on the types of shoes. Running shoes and other footwear with full length removeable inserts will work best with Stride. Close fitting shoes like soccer and cycling cleats will work best with Stride Thin. Boaing mocs and loafers without removeable inserts will work best with Stride Short. For more details, please go through the Find Your Fit page.

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 the Low, Medium and High. For those who measure 9-10.5 we offer the Low, Medium, High and Extra High.

For women with a shoe size larger than a 10.5, you 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 and see how they improve your comfort. The 30-day fit guarantee makes ordering risk free.

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 with the lower of the two arch heights to 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 top cover at 4mm. The Stride Thin and Stride Short offer a top cover 2mm thick.

In some cases yes. We have found that offering individual sizes often makes it harder to get the right size because shoe sizes vary by manufacturer.

If trimming is necessary, take out 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.

General Questions

Definitely. We accept both FSA and HSA cards at checkout. If you need a detailed receipt we can provide one upon request.

Yup. Our products are guaranteed in 2 ways -

Million Mile Guarantee - All Tread Labs molded arch supports have a lifetime guarantee. The comfort layer on top can be easily and inexpensively replaced.

30-day fit guarantee - Try our insoles in any of your shoes for 30 days. If they don't improve your comfort and alignment, send them back for a full refund. (Domestic) return shipping is included.

We do not. There are a small number of people that really need custom, but the vast majority are well served by the customizable insoles that Tread Labs offers. With our 4 arch heights and metatarsal pads, we can help almost everyone find comfort.

Everything we sell is made in the USA.

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.

Not too much. The footbeds that you heat in the oven are too soft to provide adequate support. 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 will last a lifetime and are guaranteed forever. The PU foam and antimicrobial top covers should last a year or so, depending on usage. They can easily be replaced inexpensively.

This can be easily remedied by placing some baby powder or a dryer sheet between the insole and the inside of your shoe. 

We are just beginning to roll out to retail stores. 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.

We were built to walk barefoot but we were not built to walk barefoot on asphalt and concrete. When our days were filled with hunting and gathering in the woods or savannah, our feet were well designed for the tasks. Running on pavement is a very different story.
