We continue advancing. Now we have printed a prototype of the midsole, with a density of 20%, and using the same material as in the previous test (Filaflex of Recreus). The results have improved somewhat, but we still have to solve some design problems, for better expansion upon the tread and prevent open pores that, if wet, would make sponge effect.
As in the above, we performed the test in Bilbao Makers, with the collaboration of Ivan, Jesús, Borja and Karim. The assembly Video has been made by Sergio Lopez.
