I wear a 9.5M and have borderline wide feet with fallen arches. These shoes fit like a glove out the box with a lot of space for my upper feet & toes after they swell on hikes & in the heat.  They cradle my arches with no pain.

I hike the deserts of the Southwest and use the high tops (long socks a must). The high tops support my ankles and the hard toe box supports from the occasional rock bang with no damage to my toes.  I have been wearing these for a year with many miles on them and still have tons of traction left.

Long socks are a must for high tops or the material will eat up ankle skin (dumb test trial on my end).

I will buy Oboz again.  They are very nice to my hard working cranky feet.
