I bought the 7mm to replace worn out Alien 1.0 liners. Very comfortable. Nice and warm. Thanks to the overlap design, I now enjoy getting into my Alien 1.0's without having to slip the liners on first (and removing my foot from both the liner and boot). Though the foam is not nearly as dense as the stock 1.0 liners, I get a sense that these have increased ski performance compared to the stock 1.0 liner (perhaps due to the overlap design?). When comparing these side-by-side, the Palau liners are thicker than the 1.0 liners and don't have the neoprene cut outs, hence the ankle articulation is slightly stiffer. However once I started skinning, I didn't feel any noticeable difference. These come up considerably higher than the Alien 1.0 liners, well above the cuff. These liners also fit into my TLT7's quite well, and I imagine they would make a good replacement for those boots...though I have not actually used that combination. These are moldable, but I didn't bake them. The first 3 tours felt a bit tight. However, these are thin race liners and seemed to mold themselves, and they now feel great.
