On my recent tour I was unhappy with my new shoes on my old pedals. You see, my shoes are canoes. It got me to wondering what others have set up. Clipless? Platform?Straps and clips? Which are your preferred cycling shoes? Does your shoe selection also permit substantial walking? 

I ride SPDs but there are times where I'm not clipped in, generally when I'm going slow with significant foot and car traffic around me. I've considered switching to pedals with the option of being clipped in or using just the platform side. My shoes are the Pearl Izumi Canyon MTB. From above they look like sneakers, but they have a stiff midsole. I've not had any issues walking around in them on a variety of surfaces and for periods of an hour, sometimes more. When it comes time to replace them I'll probably get something a bit more plain, no orange laces or highlights. But at the time the price was right. Having spent the great majority of my time on road bikes with Look pedals, I prefer clips to a pure platform or toe straps. 

We use SPD mountain bike pedals with mountain bike shoes.  The shoes have a sole on them that recesses the cleats, so they're easy to walk in and don't mark up floors.  

The shoes are comfortable enough to spend an afternoon walking around being a tourist.  I've never done a 10k hike in them, but they would probably handle that, too. 

My shoes are by Northwave and Robin's are by Pearl Izumi.  If you go for a shoe designed for bike touring, I think you'll get a more comfortable shoe.  The Northwave "Rockit" is a good example.

I use pedals that attach to a shoe cleat with a spring loaded clip. The pedals are often called "clipless" for reasons I don't understand.

My cycling shoes have a thick enough sole to make the cleat mostly recessed for easy walking.  With new cleats, I hear a metallic click when walking and have poor traction. I will slip and fall if I try to make a sudden direction change when walking on a smooth surface. Traction improves and the clicking noise goes away as the cleats wear down.

My preferred model of shoe varies with the season. Shimano SPD sandals for summer. Pearl Izumi SPD mountain bike shoes for spring and fall. Oversized Shimano SPD waterproof boots for winter. For the last 15 years, all multi-day tours have used sandals.

I can hardly imagine doing a multi day bike tour using conventional road bike cleated shoes that are unsuitable for walking. During tours I carry Keen sandals for long walks, but frequently walk non-trivial distances in the cycling shoes as well.

Rather ridiculously, I use spd-sl cleats which I do love for cycling, but which are probably as well-suited to walking as they are to ballet. On the plus side, I like making people smile, and they're very much conducive to that, as I skid up to the cake counter mid-ride with the grace of a tipsy baby hippo. 

For evening wear, I take espadrilles, which allow me to blend in with the normals. For the most part.

I use mountain bike shoes with SPD cleats and two-sided pedals. I’d used a variety of shoe brands over the years but a bunion began forming on my left foot last year and  I began searching for a brand with a wide toe box. I zeroed in on Lake shoes but none of the stores around me carried the brand. I called the Lake rep based in Chicago to discuss size/model and he sent 4 pairs to one of their retailers for me to try on. I ended up with a pair of Lake MTB shoe and I love them- not only is the toe box wide but it has separated, cushioned panels and a BOA lacing system that allows me to really fine tune the fit to each foot. They are pricey, but have kept my foot pain-free during long days on the road. They’re not too bad for short forays off the bike but I carry a pair of lightweight trail running shoes for walking/hiking.

Wayne, remember toe clips? We aren’t using those much these days (though they’re still available), so we’ve gone clipless with these new-fangled click-in attachments. Ergo the “clipless” pedals. I think we’d agree that by now clipless is a misnomer. 

I remember toe clips and used them for several years. But I also think that's a dumb name because toe clips are not clips. They have no retention force which is necessary to make a bent piece of metal into a clip. A strap is added to the "not a clip" to provide retention force.

The meanings of the phrases "toe clip" and "clipless pedal" are exactly the opposite of the meaning of the words contained in the phrases.

I've always ridden (and toured) with SPD mountain bike cleats and mountain bike shoes. As others have mentioned, they are reasonably comfortable to walk around in off the bike. That they don't look like "roadie" bike shoes is a plus for me.

Until fairly recently I didn't take a pair of off-bike shoes with me on on tours, but ever since my SPD shoes got completely soaked while riding in the rain all day on a tour, and I had to walk around in them to do after-ride chores, I've been taking along a pair of light, comfortable Saucony brand running shoes for off-bike use. They take up space in the panniers, but it's very much worth it to me to always have a pair of dry, comfortable shoes.

SPD-SL for my road bike, dual sided SPD/Flat for my Jamis bike I use touring.

I choose my shoes for touring for walkability and quick dry - for years was using some odd almost rubber Shimano/Michelin shoes. Those eventually ripped, now using some kind of Shimao shoe that was on closeout sale and I really like.
