14561131:onenerdykid said:At a certain point, most definitely. There's a reason why the high-performance boot world is dominated by 2-piece constructions (and ultimately why it is the only construction used in racing, but that's less important for almost everyone here). The Raichle Flexon (= Full Tilt Original) was originally a race boot - it was never developed or intended for freeskiing. But it was quickly surpassed by 2-piece boots and it couldn't keep up. It eventually faded away but was revitalized by Jason Levinthal in mid-2000s under the name Full Tilt (of which I personally consulted Jason on many times and even wore for a number of years).

But let's get back on track. Performance is necessarily linked to fit and a 2-piece boot wraps the foot much more efficiently and more effectively. When a boot wraps better, it fits you better, and when it fits you better, it performs better - and that means it does what you want when you want it to. That could be a high speed carve or it could be nose butter 3. 2-piece boots respond to your input more effectively because the fit of the shell & cuff better matches your anatomy. You will work less to get the ski to do what you want it to.
The flex characteristics of both types are quite different as well. A 2-piece boot is generally more progressive while a 3-piece boot tends to be more linear. Progressive means the boot starts out softer and gets stiffer the more you flex it. Linear means the boot starts with one feel and pretty much stays that way the more you flex it (no boot is truly linear in its flex pattern, they all get slightly stiffer when flexed, but the overall flex pattern is more linear in shape than a progressive ramp up). A progressive flex (when done properly) allows for smooth bump/chatter absorption in the initial portion of the flex curve but then can provide lots of power & energy deeper into the flex curve. This tends to be what higher performance skiers are searching for.

14561238:a_pla5tic_bag said:One thing I find hard is that I'm small in weight and also foot size, 24.5. I ski aggressively on one of Redster S9s, JJs, or ON3P magnus. Problem is, 1. it's super hard to find boots in stores that are 24.5 plus, and 2. all the boots with the most premium features tend to be super stiff. I can ski as aggressively as I want, I'm simply not heavy enough to flex high end boots. It sucks, because I want nice boots, but they're all too stiff.
14561189:tomPietrowski said:To Ski you need to be able to pressure and flex the ski, if the boots are too stiff you will not be able to flex into the boot which in turn will mean you can not flex the skis. I would say more people are actually in boots too stiff for them than they are in boots which are too soft. But going to stiff or too soft will be a problem and getting the flex of a boot correct is not as simple as going off your weight for example. The way your ankle flexes and leg length are big factors and this is why its so important to go to a good bootfitter who can asses all these elements and ensure you end up in a boot which will be appropriate for your individual needs.
14561242:captainslack said:Can you mitigate boots that are too stiff for you with leg strength training before a trip? I've still got my 130 boots from when I was skiing day in day out, but only get 2 weeks a year now and finding them too stiff.

cabrio boots are more comfortable, which is good when you spend a whole day in the park, a lot of time just standing, etc. 2 piece boots feel terrible when you are not in ski racing position.
another thing is - softer cabrio boots actually make you feel better what is happening with the skis, the terrain and everything. All this response helps you when you want to slide around stuff, instead of putting your edge deep into the snow.

14561370:JalmarKalmar said:I think properly fitted overlap boots are as comfortable as 3 piece boots.
I ain't no expert but i thought that stiff boots are more responsive.
14561372:onenerdykid said:Softer boots are simply less responsive and require you to work harder for every movement of the ski. This is not to say you need a cement block of a boot. You just need a flex that matches your weight, height, ankle range of motion, and the forces you put into the boot. From Chris Benchetler, Jossi Wells, Nicky Keefer, Bobby Brown, Megan Oldham, Eileen Gu, to the Real Skifi crew - there's not one skier on the freestyle side of our roster who wants anything softer than their proper flex.
14561495:snowpig said:I spent a lot of time and money with a bootfitter customising my overlap boots and kept having significant issues with my navicular - the 2 piece creates a lot of pressure there when flexed. Then I just bought some cabrios online, inserted my insole and voila - no more painI am never going back to 2 piece. I would rather give up skiing ?
And stiff boots are more powerful. But they don't give more feedback!!! It's like running with a hardsole shoe or running with super soft sole shoe - where do you feel the terrain better? The way a 3 piece flexes makes it feel softer and seems to allow more feedback, that's how i feel it.
14561714:onenerdykid said:And again, I'm not saying everyone needs the same flex or that everyone needs a 130. Eileen Gu and Megan Oldham are using 95 flex boots. For them, 95 isn't soft; it's their correct flex. This flex matches their weight, height, ankle ROM and the forces they are putting into the boot. It's not soft for them, it's the right flex. Everyone reading this is going to have an option that is the correct flex, followed by an option that is too soft for them and followed by an option that is too stiff for them. Going with the option that is softer than correct will cause you to work harder, put you at risk for more shinbang, and require your bones & joints to take the brunt of a landing rather than the boot itself.
14561815:tomPietrowski said:This is exactly right. So many people think they need boots far stiffer than they actually need. A softer boot does not mean its not as good it just means the skier does not need a stiff boot.
14561968:snowpig said:But , as the examples show, what stiffness you "need" actually mostly comes down to your skiing style and preference, not to your weight and height. So what other word can we use to better describe this, instead of "need"? "Like". Henrik "likes" a softer boot.
