I wear 9.5W in running shoes. The 9D here fits perfectly. Thursday says go 1/2 size less than your sneaker size and that worked well.

More about this item
Very comfortable with easy break in so far. The arch support feels similar to my Parkhurst; it started with a distinct ridge and has gradually squashed down to fit my foot shape well. The heel cup feels firm, like an engineer boot does. The sole is a nicely textured rubber.
