I bought a pair of the 2018 Roxa R3 130 T.I. and have put around 10 days on them with 2 smaller (2300 vertical feet) tours.
I've skied Raichle Flexons for around 20 years as my inbound boot and used some Scarpa Maestrales v2 for spring tours but they never really fit. I was never happy with the support of the Maestrales either.
People can read a more detailed review at
https://blisterreview.com/gear-revie...3-130-t-i-boot, but there's a few things about how the boot works that could be highlighted.
First, the fit: this boot fits myself really well and is incredibly easy to slip in and out. That should be enough innuendo. They are extremely comfortable for me out of the box (OK, more innuendo), I can wear them after skiing fully buckled. This drives a lot of my satisfaction with this boot.
Second, the downhill performance is excellent, lots of support, way more than any of my previous boots since race days. This is a 3 piece cabrio design and provides great progressive flex (more on that below). In my past attempts to try boots, I get shin bleed in all the boots I tried in the 80s and 90s (Technical, Nordica, Salomon) and I don't with these. When I tightened the settings down, they were too stiff but the simple range of adjustment let me find the sweet spot for downhill flex performance. The Church Of Flexon has gained a new abberant. I like to ski by feeling a forward balance on the balls of my feet and that has taken some getting used to with flexons so easy to get on top of the ski. These are a little different, but I've found that balance and can get on top of the ski the way I like.
Third, and I think this is what has been somewhat overlooked, the boot has really different approaches to flex and lots of flex adjustments.
This is achieved by a top buckle design and an odd little stiffness adjustment on the back in addition to the usual uphill setting lever.
Regarding the top buckle, rather than having some ratchet system or a series of notches, this boot completely relies on a large Velcro strap that loops through a single setting buckle. This works really well, both for adjusting the downhill stiffness as well as tour mode where one simply undoes the top buckle. I like the simplicity of this a lot and the forward freedom can be adjusted by either further loosening the Velcro or by unbuckling, taking the tongue out and just climbing that way.
In my few hours of uphilling, one day on firm icy crust requiring crampons and another day in softening mush, I found the forward freedom to be adequate and support excellent. Not as flexible as the Maestrales but much more secure.
The uphill setting is a lever which is kind of standard and in uphill mode it allows a little more rearward flex, but not a lot. This may change as the boot breaks in.
But the one different feature is the stiffness adjustment on the back, which has 2 settings, stiff and soft. I normally left this in the stiff setting, but on the warmer day, found that the soft setting improved both forward and rearward stride. My only nit here is that this stiffness adjustment requires an allen wrench currently which increases the transition times and fiddlyness. Relative to the Maestrale, the forward flex is almost as good, and in stiff mode the rearward flex isn't much, but in soft mode, the rearward flex for skinning is improved. Still not as good as more touring oriented boots, but acceptable to me.
Lastly, these things are ridiculously light. See the specs at blister.
Now I prefer to minimize gear; having an array of stuff to choose from to tune to a particular situation drives me nuts. So I really like these boots for a day of riding lifts and sidecountry skinning. I typically ski a 120 mm fat ski as long as I can get 1/4 inch edge penetration. I'm 6', 180 lbs, ex racer and 70s freestyle weenie with a penchant for soft snow, cool red wine and sativa.
In sum, I'm really satisfied with these boots for the fit and function. The design for flexibility from a stiff inbounds boot to a decent touring boot is key in my satisfaction. Props to the design team and I hope that my one functional nit regarding the allen wrench requirement can be fixed with a mechanism that can be set without a tool easily at transition time.
