A lift-off shoe system uses non-locking sash support shoes (30) movable vertically and spring biased upwardly in a tilt window. Sash pins (25) have heads (26) that interlock with open top slots (31) in sash shoes (30) so that the sash pins are removable from the shoes only by lifting the pins vertically from above the uppermost position of the shoes. This simplifies the shoes, eliminates damage caused by shoe-locking mechanisms, and makes sash removal and replacement simple and convenient.
