A comfy and versatile boot with no-nonsense DNA.
Lange is renowned for making no-nonsense race rockets, but the company's softened its stance—literally-—in the last few years. Its new, more accessible kicks, like the SX 90 Women's Ski Boot, are opening up the Lange line to everyone. Unlike the seriously stiff blues that made Lange famous, the SX 90 is a gentler, friendler beast, with a comfortable 102mm last that won't squeeze your feet to death, a soft instep insert that makes slipping your boots on and off breezy, and Thinsulate-packed liners that keep your toes toasty from your first morning groomer to the last tree run of the day.
Lange wasn't about to opt for comfort at the cost of performance, though. The SX 90 features the same mono-injected construction as top-end Langes, because it provides the smoothest and most consistent flex in a variety of temperatures and features the same lock-down four-buckle design that serves up the bombproof control that made Lange famous (the top buckle also features a highly adjustable Quickmacro ratchet adjustment for a personalized upper-leg fit). Inside the shell, the Thermofit RL3 heat-moldable liner will conform precisely to your foot for a snug, pressure-free fit, and the short cuff and one-piece collar contour to your calves for comfort and reduced shin bang, so you can cruise groomers, surf cold smoke, and zip through the trees from the first bell 'til the last.

Lange SX 90 Ski Boot Women's
Just to give a heads up before you read this review, I have an extremely small foot that is ridiculously wide (street shoe size 5.5 - 6), so finding the right boot that doesn't require tons of work from a bootfitter is difficult. I'm also 120 lbs for context for my review on flex. I am also an expert skier, I ride pow & eat groomers for breakfast, but I don't send it off cliffs.
Overall the Lange SX 90 fits great. The last is 102 & feels roomy but compared to other brands this could easily be mistaken for a 100 or 101 last. We're talking about mm & a stock liner that could affect this, so whatever, end of day my toes can wiggle & the top of my foot doesn't have any uncomfortable pressure.
Moving on to the flex. A 90 flex in a Lange can easily translate to a 100 or 110 in other brands so be-careful when comparing. I usually go for a lower flex with Lange because nothing is worse than having cramping calfs because you can't power through your turns. If you have more weight to you then I would suggest going up in flex. But for me, this is fine.
The liner feels average, nothing fancy here. It has comfort & fits solid around my ankle in which thats where I always have issues with stock liners. Once they pack out at the end of the season I might need adjustments.
The stock insole feels like it has high arch support, I need medium, but this is an easy thing to replace and probably for the best.
Overall this boot is great for expert skiers.
