Agreed, I can't imagine wearing shoes all day. The most pleasant footwear for me is Birkenstock Arizonas with socks, at home or office or when driving or running errands. This is the classic model with two straps over your foot and no back strap. I only switch to shoes when I will be walking some distance. With the Birkenstocks, most of your foot is ventilated even while standing or sitting, and every time you take a step the bottom of your foot gets some air. Don't over-tighten the straps. You should be able to slip your feet in and out of them without reaching down. Have at least two pair on hand, so you can easily slip out of one pair and into another. In the summer I may leave off the socks to stay cooler, so it is especially nice to switch to another pair of sandals to let them dry out. With socks in cool weather, I'm comfortable wearing the same pair all day. If you get these, be sure to get the "soft footbed" version. They are much more comfortable than the originals. And I like the suede version for the softer straps. You may look geeky wearing them, but face it, you're already a geek!
