well, i ordered them in the end of august, now, beginning of january - all insides are torn, where the ball of your foot goes, the heel area is leather, so it is still good. i have very well groomed feet, so it is not because rough patches on skin, i am average in size ans weight, i wore them only at home, every evening after work, basically couple hours every day. not that i wore them 24/7 outside for mountain climbimg... outside leather still looks like new - shiny, very soft, same colors - not faded, bottom sole is worn out a little but decent, not torn anywhere. so i do not know, i give it ok, but for the price they could come up with some better material for the insides.
