These are Satin shoe boots from the Jil Sander Spring/Summer collection. Ms. Sander started her collection in 1978 after working as a fashion editor for Petra Magazine and opening a boutique in Hamburg, Germany. Her collection started to take off during the early eighties as a result of her Simply Man and Simply Women fragrances. Jil Sander sold 75% of her company to Prada but left after having creative differences with the company. Raf Simons is currently the creative director for the company he joined in 2005 and the label is also currently owned by Change Capital Partners.
