The theory that the spring blades are faster than feet can be proven. As I said earlier, an able-bodied runner can put them on.
It's not really a ridiculous suggestion. He doesn't have to cut off his feet. He can secure them to his shins, put the blades under his feet, making him a few inches taller, and walk around in them for a few months to get used to them. He doesn't even have to compete. A stopwatch is sufficient.
If any world class runner seriously thinks he can run faster that way, he can do that, and if he succeeds you won't see any more amputated runners competing against able-bodied runners with those blades. I wouldn't bet on it myself.
