I only wear Clark pumps for work, they have a classic look and are comfortable to wear all day long.  I am usually a 9 in Clarks but an 8 1/2 normally with other brands.  I ordered the 9 but they were too small.  I was going to order the 8 1/2 but the price was a lot higher than the 9.  I chose another Clark pump instead and hoping I like it just as much as I liked this one.
