Shoes with rubber soles don't typically work very well for ballroom dancing. Most partner dances have some pivoting. If your shoes are too sticky, at best it will put a strain on your knees and ankles, at worst you risk a sprain or other injury. That's why you might want special shoes. From the perspective of the dance venue, street shoes may leave scuff marks on the floor or bring in dirt.
Ballroom dance shoes are specially designed for dancing. The shank provides an appropriate amount of support, and they are much more flexible than regular shoes. They have a suede sole (known as chrome leather), which gives just the right amount of traction to allow your feet to slide around a good hardwood floor without going out of control.
Ballroom dance shoes will cost in the neighborhood of CHF 100 and up. Dress shoes with preferably leather soles are slippery enough to easily pivot and can be found for 40 CHF and up. However with dress shoes you need to check that the sole is slippery enough, if it is not leather. You should not feel any stress on your knee or ankle when you make a full turn on your ball with all the weight on it. Ladies in particular should also consider the comfort of the shoes, as you don’t want to end a ball night early because of your hurting feet. Heel protectors are a good add-on to enhance your shoe’s and floor’s lifetime.
Unfortunately, chrome leather soles of ballroom dance shoes are rather sensitive to environmental stresses, like water, tar, oil etc. As such, their use is normally restricted to ballroom dance venues. For such dance spots as night clubs, cafeterias with linoleum or concrete floors, outdoor dance parties, etc., a pair of leather-soled dress shoes may be preferable.
Dress shoes with smooth leather soles can be adequate for dancing, depending on the floor and the shoes. Dress shoes are also more stiff, which you might not like. The advantage is that there is no absolute need to change from street shoes to dance shoes and back.
Each person is different. It may take some experiments to find a good pair of dance shoes.
