These shoes are a generous size without being oversized.  For me this is good because I have wide toes but not a wide foot.  If I size up, I'm tripping on the toes of my shoes and if I order a wide shoe, I'm sliding around in them because most of my foot is average width.  So these have worked out pretty well for me as far as size goes.
When I first put them on the seams felt rough on the inside against my pinkie toes but they did not get sore after wearing for several hours so I guess the seams softened up.  I did not notice an issue with them again.
I have high arches and plantar fasciitis and heard these shoes were great for this foot type.  I have had no arch pain so far; although, I have not gone on a serious walk yet.  I am trying to save my feet for a trip.  I will try to come back after and give an update as there will be a great deal of walking.
