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..
Second that, one of the first things I learnt after buying my first pair; no shoe trees - stretches the f*ck out of the knit. Each to their own though 9996127996️
Apparently the release of the OG Adidas NMD R1 PK is being pushed back to Jan 14th 2017, can anyone confirm this info?
