Lange was resistant to jumping in line with the other brands and slapping a BOA knob on one of their own, but eventually they did it with the new Concept line for men and women. Lange entered the flagship Concept 12 in our All-Mountain Access category for its show-stopping ease-of-entry shell design, where it was our top scoring men's wide boot--in fact, it was the top-scoring wide boot for men, regardless of category. It earned a gold medal for its trouble, though testers had no trouble at all enjoying this one.

The Concept 12 (the 12 is missing a zero, for its 120-flex, and there's an 11 and a 10 for men) didn't register a single complaint from our test team. Not a gripe about its fit, not about its skiing performance, not about the mere presence of a BOA reel (and there's some staunch BOA skeptics on the team), not about its lava lamp cuff cosmetics, and certainly not about its ease-of-entry. Not a one. All positive commentary. That's a pretty rare phenomenon for our group of crusty, boot curmudgeons.

One tester said that of all the buckles-on-top, BOA-on-the-bottom boots, the Concept 12 was both the easiest-on and the best-wrapping around the foot with each click of the BOA reel. And this guy is one of our most strident critics of BOA boots. While all the BOA systems are the same, hardware-and-mounting-wise, how a boot brand builds the boot to exploit the benefits of the dial is theirs to figure out. Testers thought that the Concept shell's molded-in "passive hinges" (aka easy-on-grooves for bootfitters in the know) both allowed the shell to gape open for hindrance-free entry and close-down in a circumference-tightening wrap when the BOA reel spooled up the slack to lock in the foot.

Testers said the fit was roomy for sure, suiting the 103mm last badging, but they said it evoked the best medium-width Lange fits (a la Shadow MV) but just a little opened-up everywhere. They said that the hold on the heel and ankles was light, but appropriately so for guys who should otherwise be in a medium width boot. For the truly thick-of-foot or those intolerant of high-compression fits, the Concept 12 would fit the bill, they said.

Speaking of the Shadow MV, one tester went so far as to claim that he thought the Concept 12 out-skied the Shadow MV 130. He did a follow-up test with one on each foot (a common testing method) and said that for him it was confirmed--better skiing than the Shadow. While we wondered if he'd escaped to the bar at lunch, the point was not lost on our test team, who unanimously agreed that this wide ride ripped. The best skiing wide boot they've ever tested from Lange was a comment that was repeated several times on test forms.

We're going to leave this review right there.

Kudos

  • “Best-fitting BOA boot in the test. Comfortable and responsive--the BOA wrapped the forefoot well and created a very skiable boot. Two thumbs up. ” -- Justin Serna
  • “Those who choose this boot will be pleasantly surprised by how it skis and feels. Great option for the wider foot. ” -- Pat Sullivan
  • “Good fit tension for a wide lasted boot like this one. The BOA is able to close the forefoot and instep nicely. It delivered good power to the skis. A great effort from Lange in the more-generous-fit category. ” -- Jim Schaffner
  • “Soft and smooth sensation around the foot. The cuff has the feel of performance. The foot has the feeling of cushioning.” -- Bob Gleason
  • “This is a perfect shape for wide, thick feet. Great liner cushioning and the tongue feels so nice. Rrrrrrrrrrrrawrrrr. Wow, Lange has done it again--a brand new boot and it’s perfect. Cushy but responsive, quick and powerful. Five stars! ” -- Kevin Gabriel
  • “Another perfect boot from Lange--it's almost getting old. This is the best wide Lange I've ever skied. Stellar wide fit--perfect for the all-mountain, high-volume athlete. No fit issues whatsoever. ” -- Mark Elling
  • “Solid and predictable. Nice cosmetics. I like the striated mat insert on the spine. Super easy to enter and exit. By far the best in the category. ” -- Steve Cohen
  • “Wow! A BOA boot that slides right on! Imagine that! Feels like a Shadow MV, only bigger. The BOA's wrap on the foot feels the best of the test, so far. Mind blowing on snow experience! Never would I have expected this category (single BOA, HV) to ski better than the Shadow! In a head-to-head test the Concept 12 out-skied the venerable Shadow 130 MV. Quicker edge to edge and stronger edge hold. ” -- Charlie Bradley
