If you're going to ride with cycling shoes, clips, and straps (double?), why not just go with a set of SPD pedals? The SPD cleats are recessed and completely walkable. Most SPD pedals are double-sided, so no need to flip the pedals. They won't drag the ground, like straps, on frames with low bottom brackets (lots of touring bikes) before they're flipped.
The only shoes I take on a summer tour is the pair of Shimano SPD sandals that I wear with Smartwool micro socs. They walk anywhere and when I hop on the bike, they clip in and I'm gone.
If you're determined to ride with clips and straps, I have ridden lots and lots of miles with MKS Touring pedals with no problems. Nice wide platform for your feet.
