The Diamar Pointe Shoe Brand
I stumbled upon this photo of the Diamar brand pointe shoe on an Argentinian website today. The toes are very interesting on this model. Instead of suede, the toes are reinforced with smooth leather. If you look closely, you can read the makers stamp on the sole, Diamar. If anyone has ever heard of this brand, please feel free to comment.
