tbh that seema to be a common problem amongst roshes, the mesh material seems to stretch over time from multiple wears, i have the same problem - maybe buy them half a size down so they fit more snug than your tts after they have stretched?
all you have to do to tell if a shoe has dropped is scroll thru instagram, all the main sneaker pages generally post a photo saying 'did you cop yesterdays drop?' or 'did you cop a W or an L yesterday?', things along those lines..
