Even in Chair Yoga we get out of the chair and do some standing poses.  I wear a size 8.5 shoe but I need orthodics  in them. So sometimes I have to go up a half size or even a full size.  I ordered these and they fit perfect with my orthotics in them!  They are super soft leather so it's like I am barefoot with the support I need.  I can do all of the seated and standing poses, not perfectly, but that would take a miracle.
