At High Heels Daily, we love to shop (and window shop!) for designer brands and fun fashion. But sometimes it’s fun to try out things that are little be more experimental. That’s why we love the “Invisible” shoe series from Brazilian designer Andreia Chaves. The heels are “a study of optical effect,” says the designer, who debuted her creations at Mercedes Benz Fashion Week this month.

Both pictured designs are available in limited quantities. Contact designer the designer at andreiachaves.com for information on how to purchase.
