I don't think EO replaces Clarks - but they are pretty close. I have pronated feet ( I live in Vionics in the summer) and Clarks are my #2 shoe, but EO is my slightly more casual shoe choice.
in Fact - I bought the EO tsv last year of the Monk Strap shoes , liked them so much - I went back for a 2nd pair about a month later...
