I am a leather loafer fan and these are fantastic.  They are a little snug across the foot at the seam but there is plenty of toe room.  I've had a pair of Aigners before and the same thing happened there.  They do stretch out and last forever, very comfortable.  If you have a tendency toward wide feet, than I would go up to a wide otherwise just wear them around the house a little at a time with socks or spray sides with shoe stretch if you can't wait.  It's a beautiful stylish loafer for white and the hardware is perfect design.
