When I read that the length of the heel of these SM shoes were 4-1/2 inches, I knew that, that height was my max in terms of comfort level. I was happy to buy them for an outfit for a Christmas Office Party.  I was surprised to received the shoes and they were actually 5 inches.  I'm a little trepidatious about wearing them this weekend.  However, they do make my legs look fabulous.  These are one sexy mamas. My husband thought they looked great and encouraged me to give them a try.  I'll see how it goes with these babies.
