EXTRA FIRM MEDICAL-GRADE SUPPORT WITHOUT COMPROMISING COMFORT. Whether you have plantar fasciitis or other foot pain, it can derail your life. Extra firm support gets you back on your feet - and back to what you love. Pace insoles deliver podiatrist-recommended firmness with precision-fit arch support and a deep heel cup that work together to decrease impact, increase stability, improve balance and reduce pain with every step. | MILLION MILE GUARANTEE. Our 2-part insole system is designed for the long haul. The medical-grade, molded arch supports are unconditionally guaranteed. Forever. The replaceable top covers can be easily replaced as often as you like, without breaking the bank. | OUR ARCHES FIT YOUR ARCHES. Most over-the-counter inserts are one-size-fits-all. We think that's crazy. Flat Foot Fred and Bella Ballerina in the same inserts? Not if they want their feet happy. Here's the reality: Whether you suffer from foot pain or just want extra cushioning on your long run, you need insoles that fit your feet like a glove. Tread Labs insoles are available in 4 arch heights - low for flat feet (fallen arches) to extra high, and everything in between. | BETTER FOR THE PLANET AND YOUR WALLET. Hate having to buy a whole new pair of insoles when your foam layer wears out? Our top covers are replaceable whenever you need. Just peel it off and make your insoles like new again without having to buy a whole new pair. You'll reduce your landfill waste and save money with Tread Labs insoles. | 30 YEARS OF MAKING FEET FEEL GREAT. Tread Labs was founded by Mark Paigen, a veteran footwear developer whose designs have sold more than 8 million pairs of arch support footwear. He began Tread Labs to improve the quality and durability of over-the-counter insoles so you can improve the support and comfort of all the footwear in your closet.
