Nice comfortable shoe except it runs a little short.  I usually take a 8.5 mens, but even with the 9 in this shoe my big toes will press against the front of the shoe even with the laces snug.  Maybe this is because my feet are on the thin side, but I don't have this problem with other shoes.  A 9.5 would probably be better but this model only comes in whole sizes.  I might try a 10 next time, though it might then be too wide.  Overall these are fine if I don't walk much in them, and the ventilation is great.  I like the black more than the brown because to me the black doesn't look too casual for business-casual wear.
