Do a YouTube search for Kangoo Jump and you will find no shortage of videos of people using the strange bouncing footwear. The question is whether it actually does any good? While the same could be said for video games and other gimmicky devices, these could actually do some harm. According to the makers these absorb about 80 percent of the shock from jumping up and down, but that is still 20 percent of repetitive stress on angles and knees.
Worse, many of the claims say it gives a “total workout,” but how does jumping up and down like a kangaroo give a total workout? There is nothing for upper body strengthening, and little for the abs. For $299, which is what these things run – and speaking of running, for the money you could get a good pair of running shoes and some weights instead; and still have money left over to download songs such as “Jump Around.”
Kinetic(Mis)Shift are products that we think deserve to be called out for their utter lack of fitness benefits.
