Ballroom dance shoes will cost in the neighborhood of $100 and up.
What shoes to wear where?
Unfortunately, chrome leather soles are rather sensitive to
environmental stresses, like water, tar, oil, spilt beer, 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. Some shoes might need some scuffing up of the bottom to make them more non-slip. Dress shoes might also be somewhat stiff for dancing, and could result in sore feet after several hours. The advantage is that there is no need to change from street shoes to dance shoes and back.
Capezio and Bloch both make sneakers for dance. They have a
polyurethane split sole, which provides lots of flexibility, and they
are quite comfortable. They work well for
the most part for latin and rhythm dances on hardwood, but they may be
too sticky for smooth dances, where you need to slide your foot along
the floor, and they also may be too sticky for linoleum
floors for any dance. There may also be some differences in the amount of stickiness based on the body weight of the person wearing them, so some experimentation may be appropriate.
