I have been lusting this pair of Alexander Wang Liya pumps for a while and they are sold out almost everywhere. They remind me of the Gwen pumps of Isabel Marant...and the heel height is 3.75 inches, a very comfortable height.
Only one size left (Sz. 37) at the Aloha online store in black for $485, get them here and I couldn't find them on a regular search....not sure why. May be best to call before purchasing online.
And another brown pair in size 35 and 36 on Net-a-porter but for $615, get them here.
Saks has them in size 8.5 and 5 for $615, get them here.
