Cool but also their products are already incredibly expensive so I can't imagine what these would cost and also I feel like this kind of detracts from the purpose of hiking.
1.1 their gear is top notch. Expensive, but it lasts in my opinion (and achieves the goal, their winter gear is incredibly performant)
2 subjective, the purpose of hiking is different for many. Simply existing in the outdoors may be enough for someone.
I have a buddy that was in a car wreck and his knee is fucked up. Reconstructive surgery and what not. He's not fully disabled in so much as he can walk and stand, but anything beyond short stairways and he's toast. He can never come hiking because of his knee and a tool like this might help, a small amount. (Which means a net positive of easy trails he can handle)
I met a medically retired marine back when I was in school that changed my view on this. His superior insisted on his group walking as much as possible with their packs, but instead of it just being extra exercise he wound up having to get an amputation after all of the stress on his legs lead to an issue with the arteries or veins. At a certain point, extra punishment isn't beneficial, and a mechanism to manage it would be useful.
