Premium arch support inserts for men and women backed by decades of footwear innovation. Eliminate foot soreness and pain with extra firm arch support. If your job has you on your feet all day, if you're an avid hiker, or if you're just trying to improve your health with walking, aching feet will stop you in tracks every time. Tread Labs Pace Insoles give you the extra-firm support you need to get back up and moving. No matter what is causing your feet to be sore--plantar fasciitis, supination, bone spurs, or even Achilles tendonitis, you can benefit from the molded arch and deep heel cup of a Pace orthotic insert. Walking, running, hiking, or just standing, the flexible cushioning reduces the impact from your soles all the way up your legs. Pace insoles are designed to replace the insoles that come with your shoes, giving you all the same room with the best support. Since they are designed to fit your arch, you may need a week to adjust to the different sensation. After, you'll notice a real difference in your discomfort and how long you can stay on your feet. These shoe inserts can be used with athletic shoes, loafers, fashion boots, hiking boots, work boots, and more! Tread Labs has created insoles to match 4 different arch heights. To ensure you get the right support, determine whether you have true fallen arches, low, medium or high arches, or even extra-high arches. Then, select the correct style as determined by our sizing chart. With the right style and cushioning, everyone of all shapes, sizes and ages can get back on their feet and enjoy real health benefits. MILLION MILE GUARANTEE: Pace's 2-part insole system is designed for the long haul. The medical-grade, molded arch supports are designed to last a lifetime, and are unconditionally guaranteed. Forever. If they crack or lose shape, Tread Labs will replace them with no charge. When the top cover wears out, replacements in your desired thickness are available and won't breaking the bank.
