Im 5'10" and wear a 9 1/2 wide in most athletic footwear and 8 1/2-9 wide in boots and I can attest to the fact foot size has no coronation to how large a mans unit will be. I'm not gonna go into detail or brag but i will say I've been told I should do many of times, and asked twice specifically to do porn/Internet porn in my life. I see it as a blessing and a curse at times as this thing has gotten me into alot of trouble in my life because of letting it do the thinking. Urban myth- busted
