This board does have an extruded base but apparently it has a structurn base as well which has small dimples in it. This board is a fast easy and very responsive board to ride. And the board floats well in the pow. Another plus is that I have u.s size 12 feet and had no toe overhang. Powder can suck but this board makes it ok to me. I love my new board and I wud recomend it to anyone who wants to go to the park and destroy some rails. Its an adrenalin machine!!
