I'm not sure if these are the kind of shoes that you can, you know, wear, but Janina Alleyne's "Exoskeleton" collection is clearly a case of form over function... in keeping with the majority of haute couture. Which is not to say that they're not spectacular, but rather that each of the three prototypes might properly be considered as sculptural objects as opposed to wearable ones.
As if six-inch heels aren't vertiginous enough, I don't know if I'd trust that additively-layered dragon claw to support any weight...
The other two styles are a little more reasonable, with the wedge heel; along with the white leather straps, they seem far more practical.
Shapeways has a little more info:
This Shoe is the Bottom Part of a 2 Part Shoe concept designed by Janina Alleyne & Modelled by INNER | LEAF. Janina Alleyne is a very talented Shoewear Design Student at De Montfort University in the UK. After advertising on Shapeways for a Shoe Modeller, INNER | LEAF were delighted to win the commission to model one of her designs. So impressed with the first model, Janina commissioned INNER | LEAF to do her entire range which included 3 shoes and a Hat.
