Sometimes old shoes from the 1990s if worn crumble. So the upper could be brand new and the midsoles looking like dry cottage cheese. A fella over at the Crooked Tongues Custom Forum thought how about replacing an crumble dry cottage cheese midsole with a new retro from a shoe with a bland upper colorway. By golly it worked. Take a look at a few pics here and visit the CT forum for entire directions on how to attempt this shoe relief yourself.
