This is the Sinclair Oxford from Tuleste Market Shoes Spring 2011 collection. These will set you back $350 bucks.
I purchased these peep toe, lace up, two-toned Oxfords for $15 bucks on clearance from Payless ShoeSource© a couple weeks ago. They're surprisingly comfortable and I feel like they look refined enough to wear to the Royal Palace to meet the Queen of England. Because really. Everyone should have a pair of shoes that they could wear to meet the Queen of England.
