I agree with BRY. You can get sticky back sandpaper from a skateboard shop online. Also, I put an extra bolt in the rear boot heel into that small plate, and an extra one under the little toe. The heel lifts but the boot never moves out of position! That said, Powershells are like crack! Not good for you, and once you get used to them, being super comfy, its hard to give em up. I tried the Reflex + R style. Front was ok, but didn't like the rear, but I might have another go after Freddie broke his ankle today.
