Yes...like the last poster said, Winwood Decksters -

Although - I own a pair, and I am not impressed at all. I found that they kind of squirm under my feet and don't feel stable. There's also the cost of an extra pair of cleats. Their surface is very not grippy. The flat side of the pedal hangs down when you get off them. I used them once, and have never used them again. That's just my opinion, but that's my opinion.
I found pedals like the Crank Brothers Mallets, Shimano m2424's, or Time XROC pedals -
To be no worse to bike on than the Decksters, and without some of their drawbacks.
Though actually changing to flat pedals definitely was better than all the other options.
There are also the "campus" style pedals that have the clip-in part on one side and a flat pedal on the other side. I don't like them because you then have to look down to clip in and maybe flip the pedal - other people have said they got used to them and didn't have these problems, but I did when I owned them.
I wish they made a power tool for taking pedals on and off...changing them isn't "that" hard but it takes a couple of minutes...
I've also seen the "EZY" pedals which supposedly let you switch between a flat pedal and an spd pedal quickly and easily -

Haven't tried them myself though, as I like the Time ATAC's cleat/pedals and they don't make a version for that.
