I teach 5th grade so I'm on my feet a lot, but not 8 hours straight. I think they're pretty comfortable. I got mine at LL Bean. They have 100% return policy so if they don't work out - even after wearing all day - you can send them back.

I originally ordered a 9 - that's what size my Keen sandals are - but they were too small. When I got the 9.5s I noticed that they have the European size on the label as well. The 9.5 is a 40 - my European size. I think the difference was that I always wear the sandals barefoot. So if you do order some, you may want to keep that in mind.
