The 19-year-old striker Feigenspan moved in 1954 from FC Nieder-Wöllstadt to VfB Friedberg in the first amateur league of Hessen.
After only one season, he received an offer from Eintracht Frankfurt and eventually signed in 1955 at the Eagles for their Oberliga South campaign.
Together with Erich Bäumler, Hans Weilbächer, Richard Kress and Alfred Pfaff he formed the attack at Eintracht.
In the final match on 28 June 1959 in Berlin, he could score three additional goals to the 5–3 win after overtime against rivals Kickers Offenbach.
Alfred Heiß, Hans Küppers, Rudi Brunnenmeier and Johann Auernhammer were first choice striker for manager Max Merkel, so Feigenspan left 1860 in the summer of 1962 after 41 Oberliga appearances and 20 goals for the Western German club Rot-Weiß Essen playing in die 2nd Oberliga West.
