Good for many things
Not just preventing blisters on your feet!  I bought a couple new bras which were perfect except there were seams on the straps that made sore, red spots on my shoulders.  I rubbed this stuff on the rough seams and no more irritation!  It's great to have on hand but hard to find in stores these days.  Amazon has it for a great price!  I hope Dr. Scholl doesn't stop making this.
