Query: Defective Product Design!

What looks like a great winter boot, fails the user test! I purchased the boots on December 11, 2011, for daily use at a Utah ski resort and within 2 months (about mid-February, 2012)the seam between the lower rubber portion for the boot separated from the upper material . . . yikes! I should've trusted the other reviewer comments warning of this defect occurring in the past. Not sure if I have any recourse with Amazon or Sorel, but I have seen Sorel boots decrease in quality over the past 20 years (I first wore them in the Alaska arctic in the mid-1980s) and will not buy or recommend them in the future.
