Three weeks ago, I picked up the K2 Raiders as my feet had grown three sizes. For the first time out I threw them on my feet, and the inside was very nice, with good dampening. I will not go into fit, as that is specific to every person. The only damage the boots sustained on the first day was minor paint scuffing underneath my toe strap.
Fast forward to the second day out, where I actually got on my first chair of the season and not a rope tow... the boots are now heavily beaten. On my left boot, the top layer of material is peeling off right beneath the bottom BOA cable. This was caused by me resting my board over my foot on the lift ride. The edge cut through the thread that tethered down the top layer to the insolation, and I am praying that is as far as the damage will go. Since I noticed why it was happening, I have stopped resting my board on my foot, and no damage progressed on the third day. Although I was really disappointed by that quality on a $200 USD boot. My $85 RIDE boots held up through that habit all through last season.
Function: The boots work well for what they are designed to do. They are made to be pliable yet stable. I was able to tailpress a rail, but I was also able to hit some medium sized jumps. They performed well. They were pretty dampening, and forgiving. Although personally, I still have some heel lift to fix, but that varies from individual feet as said before. The BOA system works well and tightens without creating it's own pressure points. I liked that aspect of the boot.
Overall I love the feel to them, but I was REALLY disappointed as far as quality has come so far.
Hope this helps anybody for picking out boots. I almost bought Burton BOA's instead, which I don't know how that would've went. The deciding factor for me on that was just what they did to Forum recently.
