The latest space boot is the M2 Trekker. These boots are smaller and weigh less than the ones Neil Armstrong wore to the moon. In them, astronauts can walk comfortably on the moon’s rocky surface. M2 Trekkers also protect astronauts’ feet from extreme cold and heat. They can be worn in temperatures ranging from –212ºC to +177ºC. They are truly more than just a shoe!
