The Plug liners will stiffen up the flex of most low volume shells. An appropriate choice for advanced and intermediate level skiers and riders. A thin, stiff, low volume, wrap style liner with an additional cuff wrap re-enforcement doe increased stiffness.
The Plug is a low-volume liner and works best with a shell fit of 1 finger (1.2" or less).
"As someone who has struggled with frostbite for an entire ski career, I pretty much attribute Intuition to saving my skiing life. The foam keeps my feet so warm! I have always loved the Plug Liner because it's both stiff and comfy- most boot shells I’ve struggled with are a non-issue with the right replacement Intuition liner in there." - Allie Rood
