For female dancers, the main concern is comfort. They usually find dance shoes too tight and heels too high. But as we see in the table below, if you want to wear flat shoes you have to compromise looking stylish wearing jazz shoes, or being able to slide and flex your foot properly if you wear sneakers.
Male dancers were more worried about the lack of options. They don't seem to love the dance shoe styles and prefer to use the same shoes they wear outdoors.
Some dancers are concerned about the cost and we generally believe that dance shoes, particularly suede sole ones, wear out too quickly. Also, we all struggle with finding the right fit!
