The Iris van Herpen x United Nude collaboration for this season has churned out a literal monster of a heel. Haven't seen anything like it before. Ten fang-like, fiberglass teeth make up the height of the shoe. From the looks of the structure, it seems like the fangs would make for a wobbly walk if your not stepping down properly.
These shoes are just off the runway right now and not guaranteed to go into production so no word on price.
