I have a lesser pair of Sidi's, Rampas, which are MTB shoes, which I love. They have a two-velcro closure system. I also have a pair of Shimano 2005 SPD sandals, which I love even more, and doubt I will wear the Sidis until winter.
Yesterday I ran a trail marathon. I lucked out, and felt a problem in the ball of my foot after about 7.5 miles and changed into a pair of shoes that had heat-molded soles, with no further problems. I was also wearing those Injinji Tetratsoks- seamless with toes. I ended up, after almost ten hours of running, with only a miniscule blister on one foot, and a couple sore big toenails, which I may or may not lose. You can imagine how I felt today, going for a 30 mile bike ride, the relief of putting on cyclig sandals, not shoes.
I've worn those sandals everywhere since I got them- never put on my "real" shoes again. Even a mountain century. Even in cold, with toe warmers inside the sandals. My feet totally love them.
