I've been wearing Dansko/Sanita clogs for many years.  Before 2011, I'd worn several pairs of Dansko clogs.  When the time came to replace them, I stumbled on this great deal for apparently identical Sanita clogs -- quite a deal for $79.95 each at the time!  So I got three pair at that great price.

When the clogs shipped, the first pair I pulled out to wear had a problem -- the right shoe was much bigger than it should have been.  Not the sole -- that was clearly the right size -- but the upper used too much material -- resulted in a shoe with too much volume in it.  The result was that it didn't stay on my foot very well while walking.  I've reluctantly worn it that way anyway for about a year so far -- too lazy to try to turn it in for a replacement.  I tried on the other two pairs and they don't seem to have that problem -- so I should be good to go once the faulty pair wears out.

So -- one of my three pair of Sanita's has a manufacturing defect.  But aside from that, I like the Sanitas just as much as the Danskos that I've worn for years.

The Sanitas are quite a steal at the moment -- $71.37 here at Amazon.  On the other hand, the apparently identical Danskos are selling for $115 at the moment here.  Sanitas seem to be a great deal.  I just hope that manufacturing defect isn't very common.
