These shoes are casual but dressy enough for work.  i wear them with my dress pants and you can't tell that they are rubber.  Very comfortable!  These are my 3rd pair of crocs.  I have 2 pairs of Mary Jane crocs in size 7 however these run small so i had to get an 8.  I usually wear a 7 to 7 1/2.  If you wear a half size then go up to the next size so you don't have to exchange them like i did.  Great customer service! I LOVE AMAZON!
