Practically speaking, the Rock shoe would make walking around rather difficult. This unusual and abstract footwear design was not, however, made to be a functional; it was created as Shoe Sculpture No. 12 within Sebastian Errazuriz's series entitled 12 Shoes for 12 Lovers.
This particular pair of pumps was inspired by a lady that the artist has called Alice. She was a very down-to-earth character with her feet planted in reality. She seemed rational and all-knowing when it came to matters of her relationship with Erraxuriz, apparently having made accurate predictions about its beginning and its end.
Modeled on a jagged stone, the Rock shoe embodies a poetic idea that ironically makes it beautiful to observe and appreciate philosophically, but challenging to use in the real world.
