Narrative:
Descending through 10;000 ft; idle; 210 kts; 12-15 kts above the foot and in a clean configuration we encountered wake turbulence from a B767 which was 8 miles in front of us. The aircraft momentarily went into stick shaker and we had a momentary autoslat extension. The airspeed never went into the bottom foot and recovered before any corrective inputs by the crew could be accomplished. We extended the slats and landed uneventfully.suggest more spacing between widebody aircraft.
