From Cool Tool:

“Powerisers are a real trip to use. They’re like walking on the moon everywhere you go. I can run/jump faster and higher than ever before. Some of the more ambitious users are out there doing flips and the like. Once I put these on I was up walking around right away. They are a lot more intuitive than you might imagine, but some people that have tried them don’t ‘get it’ right away and fall over. The hardest thing to do is to stand still, but if you keep walking it’ll seem intuitive. You can run and take very large strides in them once you get the hang of it. You can also jump very high and long.”
