One tester said the 2018 Lange SX 130 is, stress-free livin' for all-mountain conditions and we'd say that sums it up pretty good. It returns to the boot test this year with a revised, more widely lasted liner for a more open feel—though a few testers mentioned it still fits a little bit on the snug side of the wide group.
The RX LV boots are narrow. The RX boots are a similar shape and fit profile but blown-up to medium-width proportions. The SX line opens it up yet again to a 102 mm that still shares Lange family fit characteristics. Testers acknowledge the V-shaped lower boot fit that tapered gradually to the heel and ankle—a Lange hallmark. The upper cuff received characteristically Lange kudos for having a comfortable shin fit and even flex properties. However, it also got even, but snuggish fit scores at the boot top for the calf but that was with the spoiler installed. Remove the rear spoiler in the 130 for a roomier fit there. The softer flexes in the SX line come without one.
One tester said the SX 130 made flexing and edging moves at a level that was head and shoulders above the other wide rides in the group and inspired confident skiing in all conditions. This sentiment was echoed by other testers who cited its predictable, stable, no-shenanigans attitude on snow. A few testers commented that they felt a little disconnected from the ski, but admitted they didn't have the girth to fill her properly.
We think a no-fuss 130-flex wide boot that actually skis as well as it fits is a cool feature, but add to that mono-injected polyurethane construction in the shell and cuff and you've got a real boot that a good bootfitter can easily modify as needed. The Velcro power strap is a nice, fat 45 mm one and there's a single-side cuff adjustment.
