+1 for spd/mountain shoes.

I'm using Shimano PD-M520's right now, which are way too small to ride comfortably without bike shoes, but I always wear my bike shoes when on the bike, so its not an issue for me.

Another option are the spd pedals with a platforms so you have the best of both worlds. I'm considering one of these on my soon to be ordered touring bike.

The Shimano PD-M545 is dual sided, with clips on both sides.

The Shimano PD-M324 has the clip on one side, and the platform on the other.

I've been riding clipless for over 10 years now, and can't imagine riding without them!
