Tread Labs


If I am between sizes, what should I order?

If you are between sizes order the smaller size. Refer to the FIT GUIDE for more details. 

If I need to return my insoles, what's your policy? 
We have a 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. Return shipping included.
I am unsure of my arch height. What should I order?

Simply match the profile or shape of your foot print in question #2 of our Find Your Fit interactive tool. Medium is a good place to start. If you are still uncertain, please order 2 (or more) pairs to try. Shipping is free both ways and our 30-day fit guarantee makes ordering risk free.

If I trim my insoles to fit in my shoes, can I still return or exchange?

Absolutely. You can still take advantage of our 30 Day Fit Guarantee if you trim your insoles.

Does everyone benefit from orthotics?

Everybody? No. Almost everybody? Yes. As many people can benefit from some type of supportive footbed as are helped by prescription lenses for their eyes.

Do you make full custom orthotics?

We do not. There are a small number of people that really need custom, but the vast majority are well served by the semi-custom orthotics that Tread Labs offers. With our different sizing for left and right, we can accommodate many foot sizes and shapes.

Why don’t shoe companies make shoes with great support?

A number of shoe companies make efforts towards support but the reality is that with such a wide range of feet, the support necessary for those with high arches would be uncomfortable for those with low arches. That is why aftermarket orthotics are so effective.

What do you think about orthotics that are heat molded at home?

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.

What do you guys think about the barefoot running movement?

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.

What is Plantar Fasciitis?

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.

I have flat feet. Do I need support? Will these be comfortable?

Many people with flat feet benefit from orthotic insoles. Order the low arch height and try them in your shoes. You'll have a good idea of what they have to offer. The 30-day fit guarantee makes ordering risk free.

How should my orthotics 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.

Are Tread Labs insoles guaranteed?

Yup. Our products are guaranteed in 2 ways -

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. Return shipping included.

Sure-footed warranty - Everything we sell has a lifetime warranty against defects in workmanship. Molded arch supports are unconditionally guaranteed. Forever. When top covers eventually wear out they can be replaced for $15. Postpaid.

How do I return or exchange items?

Easy! If your insoles need to be returned or exchanged, please visit this page, fill out a return request and we will send a prepaid return label.

What are your "live " customer service hours?

We are here from 9am to 5pm Monday through Friday. We are in the US eastern time zone.

Do you ship/sell internationally?

We ship to most countries of the world. Shipping for 1 or 2 pairs of insoles costs $25. ($10 for Canada) 3 - 5 pairs costs $40 ($30 for Canada). Any duties, taxes or fees must be paid by the customer. We do not offer free returns on international orders.

Are Tread Labs orthotics available at retail stores?

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.

What is the fabric on top of the orthotic? Is leather available?

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. Leather has a nice rich feel but can get brittle and crack over time. We may offer it in the future, but it will not perform as well as synthetics.

Where are your orthotics made?

Everything we sell is made in the USA.

How long will my insoles last?

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.

Do I need to trim the insoles to fit in my shoes?

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.

Will my orthotics fit all of the shoes that I own?

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. None of the orthotics that we offer will work in shoes with heels higher than 1".
