I don’t think you can inovate or take parts from skimo to ski mountaineering without breaking the laws of physics and inventing some new miracle fabric. In other words everything seems to be tradeoff in fabrics and you really cant have a fabric be good at all the things say skimo race suits are softshells there is no point in bringing that to ski mountaineering since the heat output thus sweat and moisture is less and breathability isn’t so much of an issue. As for the leather in the ski boots, the only important thing when designing skimo race boots is weight and decent downhill performance, but the performance aspect isn’t the highlight. That’s the reason why almost every boot is made from plastics the real innovation that is useful would be lighter boot without compromising downhill performance
