So i stumbled across these shinbang pads at my local ski shop, and they were $29 (as expected). They were simply pads to slip into your shin. So I didn't want to spend that money and so I cut out foot insoles and slipped them in. I haven't skied in them yet, but I'm optimistic that they'll work as they felt pretty comftorable.
Short: Cutout foot insoles to slide into shins for extra padding.
