I wear the greens for everything and so does DH. The running store suggested them to us.

ETA: before Earth shoe started making some dress shoes he could wear, DH also put these in his dress shoes. You may want to ask your running store, if you are lucky enough to have a good one. They should let you try them out in the store. We were also told to come back after buying if they didn't work out. I think our store would rather eat the cost of something like that and gain a long-term customer than the other way around. Hopefully yours is the same.
