 Why don't I just use my running blade 24-7? Three reasons. Reason number one, if I did that, my body would fall apart very quickly. This blade is built to have pressure coming down on it when you are running, hopping, skipping, jumping, sprinting. When I stand up, my hips are not even because it needs to be higher on this side so that when I'm running, my hips are even. When I am just walking along, there's not enough pressure to get that spring and also my hip is out of whack. So it feels terrible and hello, lower back pain. Reason number two, this is just a lot bulkier than my everyday walking, like crossing my legs, as you can see, going up and down stairs, going through doorways. This is a lot to manage. Reason number three, for me personally, I feel so much more like myself wearing this leg. It kind of mimics the structure of a normal human leg and I can do things like put on a pair of shoes, wear pants and blend in if I'm feeling like it. Being an AFUT is very much about the right tool for the right job and this is amazing for everyday use. I like how it feels, I like how it looks and this is amazing for sporting activities like sprinting and running and doing cool things. But the second that's over, I'm back to walking on sunshine.
