Goop is good adhesive. I like it much better than a silicone and have been a user of Goop for years now. I recommend using Goop for most anything you would typically use silicone for sealing or gluing things. Works on shoes or other items. I keep some handy in my RV tool kit and not sure if the RV version is really any different than regular Goop or Marine Goop, but Goop is definitely good sealant or glue and works on shoe bottoms as a best shoe repair I have seen.
