The Free Riders are fabulous on grip. 5.10 was originally a climbing shoe company. They discovered that their soft grippy soles worked well for cycling. For earlier posters, I still don't get the need for SPD on hills for touring. Flats are fine. With my flats I'm fine spinning at 90-95 on level roads and climbing steadily in lower gears. If I stand on tour it's to stretch, and climbing out of the saddle is the only time, apart from sprinting, that I would pull up on my pedal, and if I pull too hard I pop out anyway.
I get the "SPDs are what I like" argument, and I can even buy the "they keep my feet and knees aligned" argument, but for flat ground, hills, bumpy road, etc., SPDs have no advantage over a good sticky sole and pinned flats.
