The design of the sole

The sole must copy the anatomical and helical shape of the bottom of the AKU lasts, in order to support and enhance their anatomical and dynamic characteristics.
Other aspects to pay attention to are: the reliability which must be consistent with the use for which the shoe was designed and with a view to minimal waste of material and the search for simplicity of interface/assembly between the sole and the other components of the shoe.
