For the tourer who wants serious performance and who is willing to sacrifice just a few ounces for warmth and a roomy fit.
The One PX - TF Alpine Touring Boot takes Dynafit's swift, lightweight performance and adds a roomier fit, extra insulation, and beefed-up support for the average AT powder seeker. Long, rewarding backcountry laps become the norm once you feel this boot's balanced mix of comfort and lightweight materials. On the uphill, you can achieve 60 degrees of rotation for long, efficient strides while the rockered, sticky Dynafit Pro outsole secures your advance on the skin track or boot pack. Once you click into downhill mode, its Central Buckle System locks down your heel and an adjustable Driving Spoiler creates a super-stiff structure for skiing all types of snow and terrain.
- Medium-stiff shell provides solid downhill performance without making the uphill journey torturous
- Wider last than most Dynafit models provides enhanced comfort for your forefoot during climbs and long tours
- Thermo-moldable TF liner provides a warm, flexible, and cushioned interface between your foot and boot
- Ultra-Lock System loosens the cuff into walk-hike mode with one flick of a buckle, while its buckle cable retention system prevents unwanted release
- Central Buckle System locks down your heel and creates a stiff structure for both the uphill and downhill sections
- Flex Tongue Design keeps snow out and doesn't rub during long skins, it also joins to the shell with rivets to improve rigidity
- Driving Spoiler slides into the cuff to provide up to 60 degrees of uphill rotation while preventing interior friction and blistering
- Driving Spoiler also adds a stiff structure for the downhill laps and adjusts your forward lean angle between 15 and 18 degrees
- Injection-molded Pebax cuff and shell yield lightweight, stiff performance with a thin shell and minimal materials
- Layer of expanded PU insulation glued into the shell adds comfort for the colder days in the mountains
- Short, curved Dynafit Pro sole features large, sticky rubber lugs that grip icy bootpacks and help to secure your kick turns
- Compatible with Dynafit Quick-Step-In binding systems (sold separately)

This is a great touring boot for those looking for a little more on the way down. I split them with my Dad, and we are both very happy with them. He has a wider foot (Size 11) and went with the 28.5. I dont have any experience with other Dynafit boots, so take it for what its worth. We have these paired with Dynafit Stokes 191 and they are very light! We are both around 6ft.
Is it likely these boots will fit? I have small feet (26.5) but they're very wide (103). From what I understand stuff like Scarpa will be too small, but not sure where the Dynafit boots will be in regards to width. Heard Black Diamond boots are generally the widest, but much prefer the looks of the Dynafit boots. A bit stupid I know! They'll be going to Europe so it would be best not to have to return them, and I live in a small place so not much chance to try anything on.
In a 26.5 the last width on these is 102.5 so it may be a touch tight in the width department. I would say you may be able to get some work done on them to get you there for that last .5mm but for a wider fit in the Dynafit line you won't find one at that size.
Thanks for the reply. Are Dynafit one of the generally larger sizes (i.e. in the same size boots of different companies are they one of the wider ones)? I've been told as a general rule American companies are widest, Italian ones are narrower.
Generally these are on the narrower side and that is true of most European brands with the exception of Scarpa which (in certain models like the Maestrale and the Mobe are wider) Black Diamond is probably middle of the road and then again depending on the model most stuff falls into the 98-102mm range. You will get wider lasts on the bigger shells but for your size I'm thinking 102 is probably the widest you will find in most boots.
OK- cheesy- but it really is. I converted to the TLT-5s last year and loved them. However- they weren't quite as stiff as I would have liked for some skiing out here in the east. These boots dial it pretty much just right- they have %80 of the touring ability as the TLT-5s with I'd say 30-40% more stiffness.
I still use the TLT-5s for pretending I'm a lycra clad rando racer but for the rest of the time I use these boots and find that they allow me to do more on the downhill. They also have never given me blisters. I've had problems with BD boots in the past that were properly sized and molded but still gave blisters if they weren't tightened in touring mode. I just did some long days with these boots into the 10th mtn huts and my feet were the one of the only ones in the group that didn't look like they'd been through a pencil grinder.
My only complaint is that they are actually surprisingly cold. I find my TLT-5s are warmer (strange- I know) but I have warm feet so this isn't a deal breaker.
I use them on 176 BD Drifts and 176 BD Stigmas with Dynafit TLT Radicals and Dynafit TLT Speed Radicals. I've got average feet, 27.5, and weigh 165 at 5'11''. I'd say an advanced skier but not a cliff hucker.
+: Stiff, comfy on long tours, amazing touring mode, love the soles for hiking around the hard granite of the White Mountains
-: Strangely seem a little cold, wish there was a little more rocker in the forefoot for walking (though understand this would make them not compatible with Fritschis so I guess worth it).

Previous comments are all spot on. The only question I would have is the spoiler on my pair is not adjustable as it is riveted in place, but then again maybe I'm missing something here. I'd also agree with the flex rating the previous poster provided. These boots have performed as described.
How wide are these compared to the old Zeus or Zeros? Any comments on their stiffness? I am looking for a wide, 103, stiff one. Any suggestions?
The One/Vulcan/Mercury last runs wider than the the Zzero last by 2-3mm, officially 104mm. They are not the widest boot on the market, but are similar to the Scarpa Maestrale. This is a solid boot, approx. 110-120 flex. If you are looking for more beef, try the Mercury or Vulcan. Hope this helps.
It sure would make Dynafit boot shopping easier if they put out a landscape of features and where each boot is on this topology.
Finally got to try them on....(ones & vulcan)
The lightness & stiffness was amazing, what i was looking for.
Great fit on my wide forefoot, best among dynafit boots. The back half, arch and behind was killing me, too tight, @#$@#$. Also tried on a Green Machines & ZZeus, felt better but conflicted about forefoot width. My toes feel a little too snug in these boots. Can cooking the liners on a 27.5 widen them for a 102/3 mm forefoot?
Any suggestions? How much give is their in this boot material?
Any chance you guys are going to restock the One PX in a 24.5?
Gareth: The smallest size for the One-PX Mens is 25.0. The One-PX Womens is available at Backcountry in 24.5. http://www.backcountry.com/dynafit-one-px-tf-alpine-touring-boot-womens

I finally had chance to use my new One PX boots today at Solitude; I'm very happy with how they drive my Drift 176 skis. We had ~8" of fresh powder today. The jury is still out WRT deeper and steeper but so far I have to say the One PX is a keeper. The only problem I had was with pre-release due to ice build up in the toe fitting. I'm using Radical ST bindings. Instructions say rotate the toe several times after clamping in to clear the ice but it doesn't work. I plan to start carrying a pick to clear the toe holes.
When will you guys be getting some Dynafit boots for larger feet?
Size 30.5 / 12.5 ?
Brian, Dynafit rep here. The largest size for this boot is 30.0. The largest that Backcountry ordered is 29.5. BC can order the 30, we have them in stock.
I'm sure i'm not the only size 12.5 foot out there ... thanks.
It is annoying when your ski boot choices are limited by which company chooses to even make a boot for a 6'4", shoe size 14 athlete. Right now, its Scarpa; maybe Dynafit will one day decide athletes can have big feet too. All i need is 1 shell size bigger.
There are a pair of BD Quadrants size 31.5 or 13.5 / 14 someone is selling on eBay if your still looking. 2/28/2013 good price too :)
