This is the fifth pair of Clarks Dara 3 boots that I have purchased.  I do a lot of walking at work and these shoes have wonderful arch support for someone like me that has a slightly high arch.  I've ordered some other boots from Clarks, but the heal wasn't a stacked heel, but more of a rubber heel; they were not very good at all.  I only wore them once and now they are sitting in my closet and I went back and ordered another pair of Dara 3s.  I have had goos luck with some other Clarks shoes as well and highly recommend them.
