Note that we have tested the Trinity 110 Vacuum before, utilizing a set group of custom testers who underwent the Vacuum process. This year we tested the boot straight off the rack. Results and tester commentary was almost exactly the same as previously with the exception of comments made about how forward-leaning the Trinity 110 is out of the box. This is a stance element that can be changed with Vacuum molding, so long as the most upright position is selected by the skier and technician at the time of molding. With that said, the review body that follows is adapted from last year's. The tester comments below are from this year's test.
Why do our women testers love the Trinity 110 Vacuum so much (one of the tops, second year running)? Well, look at that last width range and take a guess—it isn't the second number, it's the first. A 93 mm last width is the domain of world cup race ("plug") boots. It is tight! Some ripping women skiers may choose to try to ski a true plug boot, but not many—they're typically stiff and heavy with thin, cold liners. The Trinity 110 Vacuum is snug like that sort of boot, but with a real world expert's flex rating, lighter weight, a new and much-improved (testers said) Ultralon padded liner, and oh, yeah, that whole Vacuum custom boot thing. Vacuum is last but certainly not least in that run of attractive features. As with last year's test our women's team loved the process and result of the Vacuum protocol—with the Trinity 110 they set the cuff alignment, cooked the boot, put it on, set the stance for width and forward lean, stood still and let 'er rip! The molding process applies pneumatic bladder pressure against the boot, pressing the Vacuplast shell toward the foot and contouring around wide or bony spots and getting slightly tighter in less snug zones.
How'd the boot fit and ski? Like a glove and a bobsled on rails, testers said. The ground feel is sensitive but the boot is not weak—especially after the full cure time post-molding is achieved (skiable after 12 hours, fully cured and at max stiffness after 24).
