45NRTH Jaztronaut Aerogel Insole

45North Jaztronaut Aerogel Insole

A Space Suit for Your Feet

The 45North Jaztronaut is a pioneer in temperature-blocking insoles for cycling-specific footwear. Unlike shoe covers which are penetrable from the bottom, the Jaztronaut is constructed with a 2mm panel of non-compressible aerogel insulation that’s laminated inside durable EVA foam to provide the highest thermal performance of any form of insulation. Aerogel has been used by NASA to insulate astronaut spacesuits, as its nano-sized air pockets block out cold and heat, and its ultra-thin, compression-resistant and waterproof insulation provide the lowest thermal conductivity of any solid. When the weather it’s at its worse, pair the Jaztronaut with your favorite pair of booties to weatherproof your feet, or simply use alone when the days are dry.

Features:

  • NASA-approved aerogel between EVA foam
  • Aerogel is nano-porous and 90% air
  • Maintains insulation value under pedal load
