I work on the water & for the past decade , these thong have be my shoe of choice , but over the past couple of year I have notice quality of construction decline . whereas I could usually get 8 or so month of wear out of they before the toe leather snap , the last three pair I have own have all last only a matter of week before the side snap . because I travel a great deal , I usually buy 4 pair at a time once a year . after my recent discovery of the Colombia Tango Thong , which actually come in a size 15 , & be very well make & extremely comfortable , I can happily say that I doubt I 'll ever buy another pair of Sperrys again !
