Little screens strap onto the top of your shoes. They're bluetooth linked to a phone app that plays music that you're going to dance to.
Arrows point to which direction you need to move your feet to the music to follow the choreographed steps. Picture the Hokey Pokey.
You would be able to adjust
the skill levels, from said Hokey Pokey to River Dance depending on your level, which of course would rise with continued use of these.
