text: I own keen hiking boots.  I wanted to love these keen flip flops for summer as well.  They were just way too sloppy.  Too large for my feet.  Too much side-to-side movement.  And I do have to admit, the big toe covering is kinda weird when all of your other toes are exposed.  With the sandals fitting too large (I wear a 7.5, and normally Keen fit me perfectly.  These didn't) , and the big toe thing, I returned them.
