These are a very unique pair of heels. They are likely late 1960's. Very mod. The three straps with buttons and the pointed toe gives Edwardian revival, which was super trendy at the time, but these are pretty enough to be wearable now as a statement piece.

Shoes are labeled a UK size 5, which is equivalent to roughly a US size 7. I am a US size 7, with wide feet. I can get them on but they are tight and I do not have toe space. They would be best for someone with slimmer feet, for maybe a US 6.5. 

Has a 2" heel. Length is 10" inches and at the widest point is slightly under 3.5." All measurements are taken from the outside of the shoe, and so are subject to be off by a few centimeters. 

The brand is actually Swedish. The shoe says: "Colette Svensk Tillverkning." These shoes have never been worn before, so they are in excellent condition. There is only a few signs of age, such as a scuff on the strap buttons (pictured above) and small white dots (pictured above), which looks like can easily be covered with a black paint pen. Are very sturdy, and can be worn. The shoes are even packaged with the original store bag and the original wrapping and shoe box!
