 why I now have two running blades as an amputee. So this is my first running blade. We call her scissors because you shouldn't run with scissors. This is a fantastic blade, however it is built for sprinting, meaning that this, the blade part is a lot more stiff. I have to generate more force to run comfortably on it. While this guy right here is great for jogging as it is a lot bouncier, it doesn't hurt my body as much. So if I wanna run really quickly short distances, this is absolutely fantastic for that. But if I wanna throw on my blade and go for a jog and enjoy the outdoors, this one is where it's at.
