I recently got a pair of the C9 Lazer BOA to replace my old SS6 shoes. The S7 slide sole they came barely slid and almost launched me onto the lane during my first practice slide, lol. I replaced the the slide sole and heel to match what I have on the SS6, which was the S12 sole and H7 heel. This combo has worked well on the sticky approaches where I bowl. At first they seemed a little too slippery, but after 1 game they settled in and are perfect now. Give yours a chance to break in first and see how they are then. If they're still too slippery, maybe try the S10 sole?
