I have Keen hiking boots that fit great and I live in flip flops so I know how they should fit.  These just aren't right.  I'd return them but it's a hassle and they were cheap so I'm not going to bother but the seperator on these isn't in the right place making for an odd fit.  Maybe they will be different if they ever get worn in but I don't see myself putting up with the discomfort long enough to ever see if that happens.  Since Keen is know for their quality I have to wonder if I just got a pair that missed the QC dept.
