Product Review: Kangoo Jumps
1. They’re stupid-looking.
2. They cost close to $300.
4. Any decreased risk of injury due to reduced impact forces on the joints is offset by a proportionate reduction in ankle mobility.
This is the big one. A major selling point of the Kangoo Jumps is that whatever it is they stuck on the bottom of what can only be described as an over-priced pair of ski boots reduces impact forces for more joint-friendly running. But to quote Jimmy Smith in this article, restrictive devices like these
change the insertion point of muscles that act on the ankle. Any time this occurs, we limit the force production potential of the muscle, alter proper functioning patterns, and also cause more force distribution to be transferred to the nearest joints.
Now instead of the ankle, the joints required for mobility are the knee, and while technically not a main joint, the foot. These structures are forced to compensate and absorb higher levels of force than usual. As with anything else that has to compensate, these joints eventually wear down.
In other words, unless maybe you’re planning to take on Iron Man, you’re probably not doing your joints any favors by wearing these things.
If you want to reduce the impact forces of running…a) Run less; and b) Get your legs stronger by lifting heavy things.
I thought this was a no-brainer, but I guess not.
The verdict: Like I said, Kangoo Jumps suck. And if you buy them, you suck too. Save your money. Save your joints. Save your face.
