One of the shoes, the right one, was more narrow in the front 1/3 of the shoe than the left one.  They manage OK, but the difference is annoying, and on my first hike of about 2 hours, I nearly developed a blister as a result.  These don't offer any noticeable arch support above the basic level.  They're light and airy enough for most people to walk at least several hours without noticing them, unless the toes are a bit squished.  The footbed is comfortable enough for 2-4 hours, but anything above that and you should spend at least twice as much and get higher quality.  For what I paid and what I intend to do with them, I'm satisfied enough that I won't complain any further.  These are OK for summer and early fall, but would be too cool for late fall, winter and early spring.
