will I get any toe drag on this board with size 13 boots?
It is possible depending on the boots you run. To lessen the effects of two drag, try any burton boot with skrinage technology, this means they have built certain boots on a sole smaller platform. i.e. a size 9 is built on a sole of a size 8. Also, its a good idea to duck your stance. Try positive 12 or 15 degrees on your front foot and negative 9 or 12 on your back foot. Find the right angels and you'll be stoked.
I doubt you will have any toe drag... It has a very, very generous waist width to accommodate you.
