As I have size 8 feet, should I be looking into a much narrower tail on my shortboard? Dimensions: 5'11" x 18.5" x 2.375" (tail 14.5). My friend was tripping on how wide the tail of my board is and indeed, if he was riding my board his toes would be squarely over one fin with his heel over the other. If I place my board on the ground and put my foot between the fins, there are a good few inches between my foot and both fins. This surely must have some effect on performance. Any ideas from shapers or others with small feet?
