 This is the difference between jumping on a normal prosthetic leg and my running blade. So you can see that I'm perfectly capable of jumping on my normal everyday walking leg, but there is not a lot of bounce, spring, or energy return. So if I'm doing something that's high impact, I'm always gonna switch out to my running blade or sport blade. As you can see, there is a lot of bounce. Using this for any kind of impact activity, be it running, jogging, jumping, anything like that makes it exponentially more comfortable. I'm also way more mobile because there's actually spring. It's way more comfortable on my residual limb, also on my hips and my knee because it doesn't feel like I'm trying to land on a piece of concrete on one side. Different tools for different activities. My walking leg is the one that I use, I'd say 90% of the time, but when I wanna do some box jumps or go for a run, I always switch out to my running leg.
