Depends on the color. I know that sounds dumb but i had 2 pairs od white and 2 pairs of black. The whites held up better then the blacks. I would stay away from them if you bowl alot. I now have sst5 LX's and they sre great. No problems yet?  Each sole and heel you buy is trim to fit. They only come in size 15 i think and you have to cut them down . Also becareful NEW sole S8 is no longer leather its micro and very slick.
