Description of 45NRTH Jaztronaut Aerogel Insole - black
45NRTH Jaztronaut - The first temperature-blocking insole designed for cycling footwear.
These insoles are constructed with a 2mm panel of non-compressible aerogel insulation laminated inside durable EVA foam.
Aerogel is a porous nanotechnology that has been used by NASA to insulate astronaut spacesuits. It has the highest thermal performance of any insulation and does not require loft to trap heat. Simply put, these insoles say no to cold cleats, and yes to warm feet, even under pedal load.
Solves the problem of the sole/cleat of the shoe being too thin to properly insulate in cold temps 0 Degrees etc.. Feet so happy, now my insulated shoe covers are able to keep my feet warm thanks to these terrific 45NRTH insoles. Tell a friend.
For temperatures below 15°F (-9°C) there is the 45NRTH Sturmfist 4. Double-gloves construction, water- and wind resistant on the outside, merino wool for comfort on the inside. Available in different sizes.
