3m 5200 adhesion.  This is the real deal, used to reglue sole on newer work boots that had separated. Works great and really holds. I previously had a shoe repair shop repair a pair of boots for me and soles came loose again in a short time. The repair I made with this adhesive has already held for months, very satisfied with product. Can be messy if not used carefully, don't apply too much as it will ooze out from soles of boots if used in that application like I did. I'm sure it will work in many others.  It does have a seven day drying time so if time is an issue they make a quick cure version, but I have no experience with that version.
