Yes, I should perhaps be doing strength training, but I have limited hours to exercise and I'd prefer to spend them running rather than training so that eventually I could be running.
Another thing that happens is that your technique gets worse during longer runs, making you more prone to injuries. Maybe a device like this could either support you so you can run longer runs or compensate to make sure you don't hurt yourself.
So if this device helps with reducing running based injuries, I'm all for it
I have an electric cargo bike that I put in one of the lowest settings, if I cycle at the top speed it doesn't help much if at all. But accelerating from a dead stop is nice. This could be similar
That thing will make you sweat.
Shin splints really do suck though, I had some that put me off running for about 12 months.
There are already powered leg augmentations on the market for $3-5k, but these are much smaller.
