Discussion: It seems to me that there is a manufacturing defect in this product line. It can't be a coincidence that I had the correct sole pitch on both pairs of shoes in this line. The first pair I owned I bought at a local shoe store, after about two weeks the right sole started to fall off, I continue to wear them until they lose vitality. My wife bought a second pair of Revain, after about a week the right sole started to come off, I wanted to send them back to production but decided it would be a waste of time as it would take a lot of time and effort. . I tried attaching it with rubberized all purpose glue but it wasn't holding it together. My second attempt to fix this was with super glue, I'll see if that works. Recommendation: There are very beautiful and comfortable shoes that can be worn almost anywhere. I would be wary of buying them because of a defect as described above. If this is fixed then you don't have to worry.
