I had never heard of Zulte Waregem until they played Newcastle in the UEFA cup in the mid 2000s. As I recall Newcastle beat them fairly comfortably. The club are from the small town of Waregem in Flanders and formed in 2001. Beyond that I don't know anything about them. Lotto have made a rather poor quality shirt by modern standards although the design is quite striking. How many shirts have a cement mixer on the back? I can't think of any others.
