and unique ,,,,, I like it!!!
A bird’s skull inspired the hollow heel of these 3D-printed shoes by Dutch fashion designer Marieka Ratsma and American architect Kostika Spaho. They used the shape of a bird’s cranium for the front of the shoe, with the tapered beak as the spike of the heel. The lightweight and efficient structure of the hollow skull allowed the shoe to be 3D-printed using less material. Take a look!
