Rated 4.5 out of 5 by 6 reviewers.
Rated 4 out of 5 by the "MX factor". overall extremely impressed with this boot. BD took an awesome product in the factor and made it even better with the MX. the 40 degree range of motion in walk mode, the direct connect sole block that interfaces directly with the binding and the stiffer plastic tongue are all excellent improvements over what was already a really good boot. I was really impressed with the out of the box performance. Feels slightly narrower than the last suggests. These things will have no problems driving the biggest and baddest of skis. I was a little dissapointed to find no boa closure system on the liners, but thats my only gripe :-) my fit was 26.5 and I am a U.S size 9 in street shoes March 30, 2014
Rated 4 out of 5 by Pro's & Con's I'm 6'1 215lbs with a standard shoe size of 11 leaning slightly on the narrow side. I put my cork orthotics in the MX130 and for me the boot was tight in the heal and foot buckles needed to be backed out all the way. To remedy these simple discomforts, I had the liners heated up and molded to my foot and press/punching the top buckles out. I'm not saying everyone press/punch out the top buckles that's just what I needed. After that, the boot had zero pain points. I skinned 4 hours the first time and skied out for 30+ min. Zero issues and was loving the boot. Second outing I skied five days straight in all types of conditioned and I was very happy with the fit ,feel & performance. The security I get from having a stiff boot underfoot at high speeds and attacking steep pitches is bar none. Plus the comfort in flex/walk mode for the climbs makes this boot one of my all time favorites. Make sure you heat mold the liner and adjust the cants. Wide feet might be a challenge.

Rated 4 out of 5 by Skis well, tight on the toe box Skis pretty awesome. Feels much stiffer in flex than the quadrant (which I sent back because it felt too soft). But not as crazy stiff as my old vintage 1997 Rossi boots. No complaints at all on how they ski. Fit is pretty tight around the toes and ankles. Even after trying to thermomold them at home with toe caps, they are still a bit tight, but breaking in. My toes tend to go numb because of the tight fit. My ankle bones are pretty big and the pain went mainly away after the thermomolding, but was pretty bad initially. I think if I have a shop thermo-mold them with their proper set up most of the fit issues will be gone. I wear a street/running show 9.5 and the 26.5 length feels spot on. I wouldn't want it any shorter. My toes just touch the end when they aren't buckled and pull away when they are tightend down. A little over 1 finger behind the heel if you do the shell fit trick. I haven't skinned in them yet. But have a 10mile hut trip next weekend... January 3, 2014
Rated 5 out of 5 by Straight out of the Box After getting the liners heat molded and installing the vibram touring soles I took the Factor MX boot out for an 8 hour hike. The objective was to explore an alternate route up Mount Myra on Vancouver Island in the early season. We expected more mountaineering than actual skiing but were hoping for a few turns near the top. The turns never materialized. We started the adventure hiking with skis on our packs and finished the same way. After we turned off trail and began our route finding our pace was slowed considerably with early season conditions -just enough snow to make it treacherous but not enough to skin - and the notorious underbrush of Vancouver Island. That combined with the fact that we had a predetermined turnaround time so that we could make the kids Christmas concert meant that we never achieved the summit. Details of the adventure aside, how would I rate the boot? Well I can't speak to it's actual skiing prowess but I was definitely impressed with it's comfort straight out of the box. After 8 hours hiking up and down through the underbrush I arrived back at the vehicle with no blisters and no hot spots. I look forward to experiencing these boots with skis attached but alas we wait for snow. December 22, 2013
Rated 5 out of 5 by Great working boot Good buckles, mold-able, stiff for a big guy with pack. Liners are the best yet, though I still use custom intuitions. December 10, 2013
Rated 5 out of 5 by Up the mountain smooth. Down the mountain fast. Happy feet the whole time. I got to take this boot down to South America this summer where I did a ton of lift access hiking to skiing and it performed great the whole time, in any situation. The walk mode made it super easy and comfortable to hike and the few times i skinned they performed flawlessly. Once to the top all it took was a flip of a switch into ski mode and i was flying down the mountain, moguls, powder, groomers and air. September 24, 2013
