    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.

Amazing Insoles

I have used a Different brand insoles once before… but let me tell you. These insoles are a great investment! Comfortable and well built.

Hi Joshua! Thank you for the kind words.

Happy Feet

I have very high arches and if I spend the entire day on my feet, I have foot pain, hip pain, and back pain.I researched arch supports online and saw Tread Labs rated very highly so I gave them a try. They provide firm support and not just actual cushioning, which is what is needed for high arches.
I purchased the Dash Short Insoles and they have made a drastic difference. I now work all day on concrete floors and, although I may be tired and fatigued, I no longer limp from hurting feet and joints.
I've not had them long enough to determine longevity, but for at least one month, they still provide the same level of support as they did when I received them. Well worth the money and I am looking to buy more so I don't have to swap them out each time I change shoes.
