I currently ride on Shimano SH-R 130 shoes (this is the previous version):
I always felt Shimano shoes are wider than others (Addidas, Diaddora, etc.) and fits me well.
My feet are flat and wide and these shoes fit perfectly in size 42 (I'm 8.5 EEE / Wide in other normal shoes).
I've got the above shoes at Performance during clearance. With coupon and 10% team credit, etc. I think the total cost was below $50.
