Formthotics Ultra-Lightweight Shock-Absorbing Cycling Insoles, Single XS, Purple

[Sports insoles developed for medical use] Developed in New Zealand, a country with a leading podiatry background, Formthotics sports insoles have been sold in 30 countries worldwide for 35 years. They are the lightest in the industry, feature the advanced material Formax for high shock absorption, and utilize heat-molding technology to gradually conform to the sole of your foot. [How many grams are your current insoles?] The Cycle Single insole, size M (26cm-27cm), weighs just 16 grams. Its lightweight design won't interfere with the functionality of your bike or bindings. [Forms the shape of your feet] Using your body heat, weight, and flexion pressure, the insoles will heat-mold to the perfect shape for your feet in 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 the Cycle Single] These insoles are thinner and offer better correction than the Cycle Dual in the same series. They're designed for shoes with thin soles, such as racing shoes. [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.
