I still think that the A520 with matching sport shoe is one of the best kept secrets in cycling. Like a hybred, too Fred for the roadies and too sporty for the MTB crowd.

Release angles (adjustable) in out or up with 56 cleats. Outer platform to support the foot. 4deg of float. Can be ridden on in traffic situations without clipping in. (either move the foot too far forward to clip or ride on the back. (back is slipery though so don't ride hard. Shoes with cleats you can walk in without taking skating lessons.
