they are a peice of garbage, within about a month since i started wearing them the outer material started pealing off within two months the upper separated from the soles so i had to go to a shoemaker to sew them back together, within some few months the insoles completely wore out rendering the shoes unwearable, now mind you that i do not abuse shoes but use them in a normal office oriented enviorment, i will for sure not be buying these shoes again
