There exist several dance associations similar to Footloose. Together these these associations form ‘de zusters’ (the sisterhood). Most of the activities organised by these associations are open to the members of the other sister associations. For example, the dance competitions are open to all members, there are joint dance evenings, and if one of the associations has a (lustrum, Christmas) prom, the sisters are invited. There is a mailing list for communication. The following associations are in ‘de zusters’.
