Hi Phil, it is not insulated, just a tough plastic.
Hi Anita, those are out of production. Your best bet is a B&D comfort plate + volcano.
Absolutely Jim! These are essentially race skis which pair really well with race boots and bindings. To find a race binding that would work for you, please visit our binding finder.
Hi Kuba, you need to pound out the pin, attached either spring (depending on whether you want auto locking), and try to get the pin back in without the parts going everywhere. Good luck!
Hi Brian, yes, these are designed for race boots such as the Aliens. The 5mm is close to the stock liner so should work well for you.
