The average energy consumption for 30 minutes of walking in regular sneakers is around 75 – 150 calories, depending on pace, but with the new Muscle Trainer sneakers you can apparently increase energy consumption to 300 calories in the same interval.
So what makes Muscle Trainer sneakers so special? Well, it’s the increased weight. The average sneaker weighs between 200 and 400 grams, but Muscle Trainer sneakers will add between 1,200 grams (for women) and 1,400 grams (for men) of extra weight to each foot. All the extra weight is concentrated in the internationally-patented sole, which contains hundreds of small iron balls. However, thanks to their high-cut design that protects the ankles, and high-quality materials, the sneakers are very comfortable while at the same time working your leg muscles.
