thanks to these new sneakers, you don't need to wait for space tourism to take off to experience walking on the moon. aptly named 'moonwalker', these shoes rely on magnets to allegedly simulate walking in a low-gravity environment.
多亏有这款新型运动鞋，现在你不必排队等待太空旅行就能体验月球行走。据称，这款名为“月球漫步者”的运动鞋据称可以用磁铁模拟太空的低重力环境。
on their indiegogo campaign page, startup moonshine crea reveals that the ingenious shoes are made from an "incredibly
1 yet soft and breathable"

6 fit the unique shape of each wearer's foot.
so far the shoes seem like regular sneakers, but what sets the moonwalkers apart are the two special layers hidden beneath the memory foam, which are
7 with the world's most powerful magnets. according to the company, "each layer is made up of powerful n45 magnets that are strategically placed so the north poles face each other. this creates a repellant force, which leaves you light on your feet and happy as an astronaut."
speaking to live science, mechanical engineer patrick jreijiri, the brains behind moonwalker, explained that the strength of a magnet depends on its composition - a mix of neodymium, iron, and boron. so he chose n45, which is not only the strongest but also cheaper than most magnets. the pieces he chose for the shoe range from 2.5 to 5 cm in diameter, and are capable of moving 12 to 24 kilograms of material each.
the two special layers, embedded with 12 to 13 magnets each are arranged in such a way that the north poles of the magnets face each other. these poles
8 each other, creating a gap, or force field, between the layers. so when the wearer's foot pushes against the combined strength of the magnets, the gap will act as a cushion, keeping the wearer suspended in space. of course, there's a limit to how much weight the magnets can withstand and in the case of moonwalkers that limit is 183 kilograms.
