I had just purchased a pair of the PH's with the soft "stalking sole"---prior to my 2008 Zim hunt. In the 18 days I was there I had to re-glue the soles to the boots two separate times..and they were basically new when I got there other than wearing them around town and on a few hikes to break them in..was told the same thing--that it was a glue problem..they repaired them at no cost to me--but was really glad I had another pair with me to wear while they were drying with the new glue..guess I had thought for $300. the manufacturer would make sure the glue held..IMHO...
