I purchased this fro one specific reason and I had asked for opinions from the peanut gallery.  I have a pair of Teva sandals I really like that separated top layer from bottom layer after using in salt water.  All I wanted to do was to stick them together.  Given advice about this Goo and its described as flexible, I bought a tube.  Big mistake.  This stuff appears to be identical to "clear" weatherproof caulk.  When applied it does seem to seal the pieces together but when it dries its a visible translucent appearance, not unlike caulk one would use in a house.  It looks terrible.  A better choice would have been some sort of glue that doesn't dry all shiney.  If you do put this on a shoe/boot or whatever, remember it will look as if you caulked your footwear.  A hole would look better than that!
