Racing and touring is hard on liners. Sweat builds up; articulation causes chafing. Replace your SCARPA boot liners with a fresh pair, listed below by model.
4-Pro Flex XT - The Intuition liner for the 4 Quattro XT and 4 Quattro XT Women's boots.
Alien - Updated Intuition liner that comes with the newer Alien boots (since 2019/20). Also known as the Cross Fit Tour Lite liner.
Alien 0.0 (original) - The original Intuition liner designed specifically for the 0.0 version. Fully heat moldable and has a tongue for easy entry. Velcro closure at the top keeps it tight.
Alien 1.0 (original) - Intuition Light liner is as snug as a sock. In fact, you have to put it on before putting on the shell. Moldable, but thin so you won’t get too much extra room.
Alien 1.1 - Intuition Crossfit BT Liner for the 2nd version of the Alien 1.0 that we all refer to as the "1.1" edition here at Skimo Co. Big tongue but nothing in the back.
Pro Flex Evo - Replacement liner for your F1 boots. Also a great liner for other boots if you want a thinner Intuition liner (as compared to the Pro Tour). Women's version also available for your F1 women's boot!
Pro Flex Performance - Wonderfully warm and massively moldable, this is the replacement liner for the Maestrale RS 2.0 and 3.0 boot, blue highlights and all. Women's version is for the Gea RS 2.0.
Tour LT - And also Tour LT Women. These are the liners found in the SCARPA F1 LT and F1 LT Women's boots. Typical Intuition foam that also works great in other boots.
Hi Luke, it depends on your fit. The Alien liners are a lot thinner so if you didn't have much room in the shell they would work great. The Pro-Tours are thicker, heavier, and don't articulate as well.

Question from
Patrick
How does the Pro Flex G liner compare to the Pro Flex Evo that comes with the F1?
Hi Aljaz, yes it's possible. Note the 1.0 liner is thinner so there will be more space in the boot which may affect your fit. We should also have more "0.0" liners later this fall.
Hi Anthony, the Alien liners are a bit thicker than the Syborgs, which may be considered an upgrade depending on your perspective. The 1.0s would be a fairly negligible difference.
