 I need a running blade when I have a prosthetic that works perfectly well. This is a question I get a lot and it's an understandable one, so I'm gonna demonstrate live. I'm sacrificing my body for you. I hope you appreciate why it is so necessary to have the proper equipment to ride. So this is what it looks like when I run on my walking foot. So as you can see, there is absolutely no actual bounce. There's no energy turn coming from this leg. Not only does it look terrible, it's also very, very uncomfortable. I feel so much pressure in my knee and my lower back and my hips because this is not built for that kind of motion. Inefficient, painful, and slow, which is why. We use running blades. This is one of my running blades or sports blades. It's actually built to have the energy returning to allow me to have that spring in my step where I can actually run. So running blades actually have that spring and that bounce allows you to be able to run more comfortably. See how I can actually get some bounce because it's got that spring. I do indeed dream of the day where maybe there'll be like an all-in-one prosthetic that works for absolutely everything but for now we have different tools for different jobs.
