Clarks are great, but the heels seem to be a problem fit-wise.  These shoes were comfortable and fit right out of the box until I began to walk in them, when the heels slipped a lot, despite the laces being tied as tightly as possible.  I guess the style is just wrong for me, which is very disappointing, since I like them so much.  The shoes are attractive and if it weren't for the heel slip I would have definitely kept them.
