Description Available in: Heider SV is a German association football club from the city of Heide, Schleswig-Holstein. The club was founded 14 October 1925 by what was the reserve side of VfL 05 Heide. The reservists thought they were the better side and challenged the first team to a match, which they won. Despite this, no changes were made to the first team roster, so the reservists left to form SV.
