I have a lot of Keen shoes, especially Keen Venice sandals, which run wider than these but aren't as nice for wearing with dresses.  The first pair I ordered I had to send back because the straps were attached slightly differently on the left and right shoes, and while the right shoe felt great, the left shoe was pinching. They were also a little too big.  So I ordered a half size down and they're fine in the length, and the straps are the same on L and R, but I suspect I'm not going to want to wear them all day, the way I wear the Venice sandals.  The fact that there's an unadjustable strap under the top strap doesn't present a problem for my feet, and while the arch support isn't fabulous, it's good enough, even for my flat feet.
