The first pair I ordered only lasted a few months before the right insole came loose.  The insole is no longer attached to the shoe and has slipped about a 1/2 inch towards the heal.  I have tried to reposition it, but without a glue of some sort, it will not stay.
I took my 2nd pair out of the box recently - will let you know if I have the same problem.

I have always been a fan of Avia sneakers.  I have finally retired my old ones (had for 8 years) and bought these.  I am ordering a second pair today!  These sneakers are very comfortable and do not need breaking in.  LOVE them.
