I probably have purchased over 25 pairs of Clarks and these are the worst.  I knew the big elastic gusset in the back was not very attractive but I thought it wouldn't matter if I hid them under slacks or jeans.  And, I would have to say that the fit is pretty much perfect.  The problem is that the sole seems to lack a shank and there is no support in the arch of the boot.  It is so bad that you can feel the front edge of the top of the heel running under your arch.  Imagine putting a pencil under your arch and walking on it, it is nearly that bad.  But, I waterproofed them and wore them out in a Wisconsin blizzard so I am stuck with these miserable, painful boots.  I will go shopping for a thin, rigid orthotic and hope that it will protect my arch from the heel edge.  Otherwise, they will go in the donation bin.  I am so disappointed!
