text: I have a pair of these that I have almost worn out which are a size 7.  The new ones state they are the same size but are clearly much larger like an 8. I don't understand how sizes can change. I love the shoes but now I am stuck with these that do not fit.  We live in Panama so for us to ship from Panama to the US to exchange them cost us more money.  Not sure what to do at this point.
