I ride in Horse Shoe riding sneakers by Ropers.  They are cheaper 
than Ariats & fit my foot better.  100% leather, so the cuffs don't 
wear out like on some riding sneakers (such as Steel Riders).  I put 
an Ariat gel foot bed in - COMFORTABLE!
I would suggest changing out of the 4 bar stirrups!!  (Been there, 
done that, won't do it again!)  I'm riding in the Trail Tech stirrups & 
love them.  Look for a foot rest of AT LEAST 4" with a closed cell foam 
pad.  Most stirrup makers are making bars to accommodate a variety of 
widths of stirrup leathers.
To improve circulation to my feet, I do "toe lifts" whenever I think 
of it & the pace permits.  At a walk, I try to take my feet out of 
the stirrups briefly, or get off & walk for a bit.  Also, make sure 
that your shoes are large enough so that they don't constrict your 
foot.  Your foot swells a bit as the day goes on, which can also 
restrict circlation if your shoes fit too snugly.
Hope that this helps.
