I also have worn boots for the last 27 years. I sail mostly in lakes and most of the launch areas are sand/mud with rocks & glass. From all the cuts I see on the bottom of my boots, there is no question that they are a good idea. Less feel of the board? Possibly, but I don't seem to have a problem. No cut feet, no blisters, no raw places, no jammed toes.
If you only sail off a clean sandy beach, I can see why you may not want boots.
