I started wearing Dansko clogs at the recommendation of an orthopedic physician who specializes in feet and ankles.  I was having persistent pain in one foot.  This recommendation came after months of seeing a podiatrist who had me literally in a cast several times, a walking boot for months, told me not to walk, made unnecessary and expensive orthotics for me, etc.

After I started wearing Dansko clogs the pain went away and I'm back walking many miles a week.  The orthopedic physician told me to wear rigid soled shoes (and no mules or slides without a back to the shoe.

Danskos are well made.  I bought four pair.
