Bloch's Neo-Flex Jazz shoe includes a leather upper with a neoprene mid-section to hug the arch of the foot. The split sole allows the dancer freedom of movement and has a rubber bottom. This jazz shoe comes in both a narrow and medium width due because it is wider in nature.
Manufacturer guidelines suggest same size or 1 size up from street shoe. This information is merely a guideline. This does not take into account dancer preference.
