How will future space suits differ from the current ones? As space is explored, footwear for astronauts is keeping pace. NASA claims their new soft boots are designed for real walking.
Currently, astronauts don’t “walk” in space. They hover and float, or their feet are placed into foot restraints so they don’t drift away. Space suits are somewhat flexible; they can bend at the knees and rotate at the waist. But no nuanced space shuffles or relay races quite yet.
Ever ahead in their thinking, NASA envisions that astronauts will go to Mars one day. With that prospect, they need to be suited up to explore alien terrain on foot or in their vehicles. NASA’s soft boots will take them there.
