I had purchased Dansko clogs in the past and they always required a "breaking in" period. So I was a little concerned with the boots, but they fit perfectly and comfortably from day one. I have worn them all day and did not have any issues. They fit true to size and can be adjusted with the laces for larger calves. They are extremely cute and very well made. The footbed is not lined, so in colder climates you may need to add an insole for warmth. Great value for the price!
