Airport; Human Factors; Weather
Runway was extremely slick. There was nothing on the METAR or the NOTAMs that indicated the braking action. The 210 overran the runway end by 8 feet. Local Airport Manager and his handyman helped push it aircraft onto the pavement. The maintenance personnel after looking at the airplane deemed nothing was wrong so [I] departed for destination airport.  No anomalies or problems found with gear; no prop strike occurred.
C210 pilot reported running off the end of the slick runway after landing.
