I've always been able to buy shoes on line because my shoe size has been a very consistent 5.5 for years.  I had to return these because they were way too small.  I returned my 5.5 for a 6 and the shoes still feel too small.  The foot bed is just structured differently, and I can't find comfort.  Because they run small, they want to slip off my feet constantly.  I have given them time to get broken in, but I won't be wearing them much longer.  I was surprised a Clarks product was so different from what I'm used to.
