Love these sandals.  My 4th pair from White Mountain.  They wear extremely well.  I've never tried to have resoled but they probably can have the rubber tread glued back on.  The beading holds up great for daily wear.  Never had one of them come apart or break in any way.  Year round use in AZ and I can get close to 2 yrs out of a pair.  Only negative is they are narrow in the forefoot.  I have slender feet but my forefoot is squeezed into the toe box.  I always have a break-in time for the pinky toe to wear a soft spot on the insole edge.  I don't recommend planning a long walk in them right out of the box.
