How will future space suits differ from the current ones? Well, for one thing, the boots will be made for walking. Astronauts who wear space suits for extra-vehicular activities (EVAs) don’t walk. They hover and float, or their feet are placed into foot restraints so they don’t drift away. In the future, however, astronauts may go to Mars as part of NASA’s new vision. And they’ll need very different boots to walk on the planet’s surface or drive a rover.
