I purchased my Brown/Black World Leaders in July of 2011 at Rockport Outlet store in NJ. They were and still are the most amazing everyday shoe I have ever worn. Hot or cold weather, they keep my feet comfortable! Great Job Merrill! They are only now showing some perforation of the tread material at the side of the heel. Now If I could only find them again. Have they been discontinued? I have just ordered a pair of World Ramblers online and hope they give the same level of performance and comfort. Thanks again for making my shoe purchase an easy choice.
