Very easy trophy, this is how I got it. Go to "Racebox" and set up a zone battle game and put the target on 55 and the A.I difficulty on Elite. Now don't use boost, you will want to use all your energy on your shields, which are used by pressing and then pass through the hexagons (barriers) that the A.I leave behind. You need to pass through them while your shield is on as if you don't it will just damage you and you won't go through it. I recommend doing this on Anulpha pass then you can go on the overpass as there's usually 2 or 3 up there. You won't know when you've gone through 15 unless you count them but as soon as pass through the 15th one with your shields on, the trophy will unlock.
