I need width in the toes and have a high arch and wide ankles. The tendon on the front of my ankle demands a lower-cut shoe. Haven't found accommodating regular bike full shoes yet.
I wear my Keen bike sandals year-round. The sole is stiff under the cleat but has flex elsewhere.
Some say the toes run narrow on the Keens. Try before you buy.
I love having the loose sloppy fit, just make sure it's snug enough to clip out.
I also love that I can adjust the width to accommodate thin summer cycling socks -vs- heavy wool winter socks plus a thermal toecover (worn between sock and shoe).
