About this item

• [Sports insoles developed for medical use] Developed in New Zealand, a country with a leading podiatry background, Formthotics are sports insoles with a 35-year global sales track record in 30 countries. They feature the industry's lightest weight, advanced material Formax for superior shock absorption, and heat-molding technology that gradually conforms to the sole of your foot. [How many grams are your current insoles?] Run Single (26-27cm) weighs just 18 grams. They're incredibly light and don't interfere with the functionality of your running shoes. [Molds to your foot shape] Using your body heat, weight, and flexion pressure, they heat-mold to the perfect running shape for your feet within about two weeks. They can also be reheated with a hair dryer or other heat-molding device. Their precise fit reduces blisters, arch support, heel cup support, and knee support. [For those who choose Run Single] These insoles are thinner and stiffer than Run Duals. They're perfect for shoes with thin soles, such as those used for racing. They're designed for runners who can run a full marathon in around 2-3 hours. [How to use] The special material, Formax, molds to your foot shape in about two weeks using your body temperature and weight. Start by using it for a few hours a day.
