Slide on is formulated TFE - a slipperier relative of teflon.

  Spray lightly inside your boots especially the rear where the heel slides down, the underside of the tongue and the foot bed.
  Two light coats are better than one heavy coat.

  Slide On dries in seconds. It is tenacious and sticks to the your liners like spray paint. It is colorless and will not build up.
  One application will last a month of heavy usage.

  Use Slide On anywhere to eliminate light friction.
