Bought these shoes for my husband for his birthday, he has worn them to the gym 4 times. Literally 4 times! They fell apart to the point where my feet blistered after the 4th wear. If he didn't have other shoes with him, he would need medical attention. I contacted Puma about this and all they had to say was that the insoles are for replacement. I told them many times that the problem is not the insoles but the shoes themselves, they did nothing. They don't care that they are making a product that harms people. Don't buy a puma! Shoes fall apart after 4 wears. waste of money. Worst customer service I've ever dealt with!
