I own 2 pairs of Dansko professional clogs (that I have had for 8 years), the Sunny sandal & the Sela sandal.  I love the arch support of the Danskos.  BUT the Sela has an elastic part that is by the buckle.  Both shoes within less than one summer wear - have the elastic part shredding - rendering the sandal completely useless.  It was the biggest waste of my money and I am completely disappointed in the quality of this particular Dansko item.
