we like the idea of these massage sandal . however , they be poorly design because the tiny massaging peg come loose and break off not long after we start use they . my wife and I be not overweight people -lrb- athletic build -rrb- and only use these sandal around the house -lrb- not for hight impact activity -rrb- . we be both very disappointed with this product from a name brand company like Adidas . we would not recommend this product for anyone since they begin break so soon .
