I haven't found a great slip-on shoe for work yet but this one is my go to shoe so far.  I've purchased this show two times before this purchase.  They last about 1 1/2 years with daily wear before they start looking worn.  I usually wear a size 9 shoe but I ended up getting an 8.5 ... so they run a half size big for me.  I have a pair in brown and black.  I would recommend this shoe given the price.
