Proper Foot Support and Alignment
I have flat feet and wear custom orthotics. I transfer them from shoe to shoe, including cycling shoes. It’s a pain. Then in 2017, Bontrager came out with cycling-specific inform BioDynamic Insoles. I bought my first pair weeks after they hit the stores and have bought additional pairs since. Yep, I’m lazy. It’s easier to have multiple pairs, than to move them from one cycling shoe to the next.
Partnering with Superfeet, a company with 30+ years of insole making expertise, Bontrager designed an insole that provides complete support across all three arches of your foot. Using a dual density design made from EVA foam with a hard nylon cradle, it provides support across the transverse, lateral, and medial arches for proper knee alignment. Bontrager’s proprietary 3D Arch aligns and stabilizes the foot for more even pressure distribution and maximum energy transfer.
If you suffer from hot foot, these insoles have a footrest metatarsal pad that helps to reduce or eliminate hot foot. Note that not all foot issues can be resolved with an insole, bike fit including cleat placement might be in order, too.
Bontrager suggests you visit a Trek store to be measured for the proper insole arch height. There are three arch heights to choose from; low, mid and high. They are numbered 1, 2 and 3 and corresponding colors. Each arch height comes a variety of sizes from 36-48.
Since cycling shoes are all shaped a little different you may need to cut the insole. To get a custom fit, remove the insole that came with the cycling shoe, trace it over the Bontrager insole and cut to size. I use the #1 low arch insole and have yet needed to trim them. But your experience could vary.
Like all Bontrager products, the insoles are backed by their unconditional guarantee. So, if after 30 days you decide they aren’t right for you, take them back. For a good visual and more information, checkout Bontrager’s short video on their inform BioDynamic Insoles.
If you are looking for an inexpensive way to have better performance and happier feet, try Bontrager’s inform BioDynamic Insoles. They were introduced in 2017 in partnership with Superfeet and are designed to be cycling-specific. The insole supports all three arches in your foot, preventing arch collapse. Proper support translates to increased comfort and better performance. I’ve purchased a pair as soon as they were available at my LBS and my feet definitely feel better supported.
