These sandals, imo, are significantly worse than the earlier model.  My previous Keen cycling sandals (chewed up by a new puppy, sadly) had a better lacing system.  That system included a velcro strap across the top of the ankle, and was much easier to put on and take off.  Also, the new spring-loaded cord latch has a button on top, which presses into the top of my ankle.
Also, these new sandals press into the outside of my foot, in the arch area.  They seem to be built up there, maybe for support?  At any rate, it makes them uncomfortable.
