A digestive disaster spurred another rebuild.  If they were shoes, they would have to be destroyed.  Fortunately, the sandals could just be disassembled & washed off.  Replaced the laces, since they still retained a brown shade of sorts.  It's either old age, lack of will power, or extreme food poisoning.

The old plastic system returned, as well as the suede.  The Target insoles don't last long.  Suede had issues folding up, so it got laces through it.  The lace protectors wear down so fast, it's easiest just to replace them on the sandal.  Having plastic going across the sandal only felt like running on top of strings.  

The Vibram soles showed slightly less wear than a shoe.
