I gave these a 4 star review last summer, soon after I ordered them in early August. I've worn them probably 60-70 times between last summer and this summer, and taken very good care of them (e.g., storing in their box when not wearing). Today, the cork around both heels started cracking and crumbling -- a big chunk fell off one and the other seems to be headed in the same direction. They otherwise look nearly new. I have not worn them in the rain or abused them in any way. So disappointing. I've seen reviews on line that some Dansko clogs have problems with crumbling soles, but this is the cork (or &#34;cork-like&#34;) material. They are now unwearable. I would expect Danskos to last for YEARS. Sadly, I have a 2nd pair in another color...worn less...now I'm afraid to wear them because who knows when/where they will fall apart.
