I  wear 8.5 in most shoes, I like to size up 1/2 for athletic shoes, I purchased a 9B.  I had to return to try 9.5 a full size larger and I went for D instead of B.  The top and sides of my toes felt cramped with no socks!  Amazon had one in stock left, hopefully my foot won't slip in the heel or roll to the side with the larger size and width. 3 stars for padding  with out bulk and style.
