High-quality single Normatec compression boot in unused condition.  This is a very large-size compression boot.  The top of the boot measures 22 inches in diameter without inflation, and the overall length of the booth, without inflation, is 28 inches.  I put "XXXXL" in the title to emphasize the very large size of this boot, but this boot does not have any size or manufacturer tag on it anywhere.  $12.99 flat rate shipping or free pick-up in State College, PA.  Normatec compression boot is guaranteed to please or your purchase price cheerfully refunded.
