Footballtennis, also known as futnet, is a sport originating in 1920s in Central Europe. In German it is called Fußballtennis, in French tennis-ballon, in Hungarian lábtenisz and in Czech and Slovak nohejbal.

In 1922 the members of the football club Slavia Prague started playing a game which they called football over the rope, because it was initially played over a horizontally suspended rope, which was later replaced by a net. Usually two or three players on each side could touch the ball three times (not two consecutive touches by the same player) with all parts of the body except for the arms and could let the ball bounce once between the touches, altogether three times before passing it on the other side.

In 1940 the first official rules were written. The first futnet footballtennis cup was played in 1940 and between 1953-1961 first league called Trampská liga was played. In 1961, futnet was recognised as an official sport by Czechoslovak Sports Organisation (ČSTV) and the Prague Futnet Commission was established. In 1971 the "Český nohejbalový svaz" (Czech futnet footballtennis association) was founded.
