Were they your regular size? I've noticed my feet shrink when my feet get conditioned from running, but swell sometimes too (inflammation?). I just figured out I can control the tightness by loosening or tightening the lacing (duh)
yes these were the correct size and fit fine, just not a lot off support or cushioning, not sure what happened. maybe they were compressed by the previous owner. I'm just used to a lot more support.
