Soft sling sandal on a wider platform - perfect for at least 3 toes of the same length - 80 mm heel and leather lining, dance sole made of untreated, non-slip smooth leather (open-pore) - so you can also put your tango shoe on with your summer dress outside.
Have you ever walked in fat or dirt? Then just sand it down with a fine emery. So you always have a good grip on your sole.
Good padding and all materials non-toxic for your barefoot dance experience! :)
