That’s according to one of their ads. I haven’t seen that particular ad, but I read about it in the NY Times, so it might be true.

I did see one TV ad claiming the new sneakers tone leg and buttock muscles better than regular walking shoes. Is it just marketing BS, or could it be true? A lot of people seem to think (or at least hope) so. Sales are smoking hot, just like your legs will be.

Reebok says the EasyTone is their biggest hit in five years. And no wonder. They were designed by a real rocket scientist, former NASA engineer Bill McInnis, now Reebok’s head of advanced innovation.

But what about the controversial claim? Can the shoes live up to the boast? According to the Times,

“The claim is backed by a single study involving just five women, walking on a treadmill for only 500 steps. Some wore the EasyTone or another Reebok walking shoe, some were barefoot. Sensors indicated that the EasyTone worked glutes 28% more than regular walking shoes. Hamstring and calf muscles worked 11% harder.” (Edited slightly for length, clarity and emphasis.)

Wait — who cares if your leg and butt muscles work a little bit harder? All we want to know is, do boobs really get jealous?
