Previous versions of the Keen commuter sandal were really narrow and I couldn't wear them. This year, the redesign that produced the Commuter III is really a great sandal. The trick that makes them a pretty good bike shoe is the velcro instep strap. I find it's pretty important to pull that tight to make you snug in the sandals. Then the lacing of the toes really doesn't matter. I had some Keen's (the non Commuter version) that didn't have that strap and they were pretty much worthless.
Really like the new version.
