I bought a pair of Grant Stone Brass boots in size 8, 0.5 down from my Brannock size of 8.5. Although there's not much heel slip, there's a significant amount of space between my toe and the tip of the inside of the boot (at least 0.5 inch). I contacted GS with pictures and they said the sizing looks good but I have room to go down 1/2 size (but might be a bit snug). Should I bother sizing down? I've attached some pictures showing where the ball of my foot is while wearing the boots and a pic showing the space between my heel and heel counter when my foot is at the tip of the boot.
