I am looking for a general guide to tell you how to authenticate a pair of heels. I have read where of course everything is high quality, about the certain font, about the stitching, etc. One question is: everything checks out for the exception the "Made in Italy" is NOT stamped in next to the tag on the inside of the shoe. Does that mean they are fake if it's not written in the sole?The PRADA tag is in the correct script, and is sewn in.
