Keen has always made a comfortable shoe/sandal/hiking shoe and I have owned them all, it seems, over the years. these look a bit like a rubber shoe, there not. One gripe, but not a huge deal; the pause/resume button/function on this set is wonky and unreliable with Double Twist which is the main app I use to listen to music. I have a horrible time getting shoes to fit. I would definitely buy this again. Attaching the cushions is easy! I tested the mic with friends as well as via a playback and its very, very clear without backgrouns noise, crackling or static. It is so tall that the top of the portion that covers the heel digs into my achilles when I walk, and these shoes are not incredibly flexible, so it hurt! The only thing I did not like was the T-bolt that is use for the bike frame clamp. Dimensions were as advertised.
