Fuck, are you idiot?
You just said it, that liner have been the best for over 20 years and still is. I dont know any liner that provide warmness and comfort like these. I really like the boot system with cable that doesnt kill my ankle like buckle used to do it when I tighten up the booot.
That being said the SPK liner sucks. The spk weight a ton with that added leather, even more when it become wet. But yeah every pro rocks them, they looks c00l, they must be the shit and fit everyone. They are the revolution(Park specific boot, how the hell could people ski park before these were made), they also make you better at skiing. buy them. reallly, buy them without trying them.
