K2 Thraxis Boot Review

thaxis-blk
$399
Advanced to Expert All Mountain to Freeride
Were you worried that Burton was one of the only companies to make a boot over $300 well never fear.  K2 stepped up and threw in all the tech they could to compete in the $400 boot range called the K2 Thraxis.  So is it worth it?  We can't say for sure but we will say the K2 Thraxis is a well made high end All mountain to freeride snowboard boot for people who need more lace up speed than a regular BOA snowboard boot. Unlike some BOA boots K2 makes a very dense liner to shield you from the pressure points a boa lacing system can cause if you tighten it up really tight.  The strange thing about the Thraxis is they have 1 BOA for the liner, 1 BOA for the upper and 1 BOA for the lower.  Even with 3 BOA coils it's still not as adjustable as speed lace or some traditional lace boots because the upper and lower aren't completely seperate like some BOA Boots.  but it is one of the the easiest BOA to take on and off. No one else in the industry does this but it's an interesting idea.  K2 always seems to have different designs for their boots and bindings. In the case of the traxis the design doesn't hinder the performance.  The Traxis is a solid performing boot.  Is it an equal to the Burton Ion or DC Status?  tough call.... We will say that the Traxis is one incredibly comfortable, responsive and easy to adjust boot so if it appeals to you then go for it.

The Good Ride Take

 The Good Ride Take on K2
K2 is a big company that makes a lot of ski and snowboard gear. K2 chose Flat Camber and variations of flat/rocker for their snowboards in the post camber revolution. Their flat camber has a mixed take but their flat/rocker shapes seem to be well liked and some are Good Ride Favorites. When it comes to Bindings K2 spends a lot of time working on the quick strap/release side of things and they have 2 quick release designs. Some like this but others would rather see them work on improved turn initiation, comfort and better board flex under foot. We’d at least like to see them switch to only one quick release and develop their normal bindings more. Their boots are well made, long lasting and comfortable but some don’t have the adjustability that some boots have. Their customer support is very good but there is no phone # on their site so you must contact them via email. All in all K2 does a pretty good job when it comes to making snowboard gear for a wide variety of riders.

Compare Laces & Sizing

BOA vs. Speed Lace vs. Traditional Lace
A Snowboard Boot Lacing System Comparison by The Good Ride.

The Good Ride Take on BOA Boots- A BOA Boot has a steel cable attached to some sort of plastic Coiler mechanism that tightens the boot instead of laces.  There are 2 main types of BOA boots.  
1. Single BOA- This uses just one BOA Coiler to adjust the entire boot.
2. Double BOA - This uses 2 BOA Coilers for upper and lower adjusting.  Some have 1 for the outside and 1 for the inside but most are for upper and lower. 
BOA boots are the easiest to get on, get off and adjust out of any boot.  Single BOA boots have the least upper/lower adjustability of any boot because the bottom and top is tightened by one coil. If you have a Double BOA (2 Dials for upper and lower) they are closer to other lacing systems but still not as good.  Both the upper and lower dials adjust the ankle in the same place.  This means you don't have complete separation like you do with Speed Lace and most Traditional Lace Boots.  The biggest issue with BOA boots is if they break it requires a shop or the manufacturer to fix them.   It’s usually not the cable that breaks but the dials.   Out of all the boots you can crank a BOA tighter than any other boot which can be a good or bad thing.  There have been some complaints that BOA boots can have some pressure points from the cable system when tightened too tight.   The bottom line is BOA tech is a cool technological advancement that will work well with many riders and is super easy to adjust.  In the end it comes down to personal preference and BOA could be right for you.

The Good Ride Take on Traditional Lace- Traditional Lace is what most people know.  It’s reliable and easy to repair.  Lace boots take a lot more effort than BOA or Speed Lace.  Also many riders complain about blisters in attempts to get them tight.  Some Lacing systems have handles at the top that connect to the laces and we love this.  Another thing we like is when the upper lace hooks hold the lace in place so each section can tighten independently.  When you have this along with a handle connected to the end of the laces it’s more adjustable than BOA and Speed lace.  We really like this but it’s almost not a traditional lace boot.  It’s more a hybrid but whatever you call it we like it!  However it’s not great in terms of the time it takes to get things dialed out or make minor adjustments on the hill.

The Good Ride Take on Speed Lace- Speed lace is a perfect compromise between BOA and Traditional lace.  It’s almost as fast as BOA and more adjustable.  Some Traditional Lace is just as adjustable but speed lace is easier to do so.  We really like how the upper and lower laces are 100% separate. This is a huge advantage over BOA Boots and some traditional laces that don’t lock at each hook.   Speed Lace is super easy to tighten up and dial out.  It’s also pretty easy to make small adjustments throughout the course of the day.   If the laces break out on the hill it will be a lot more difficult to fix than traditional laces but it can be done without help from a shop or sending it back.   If you are a 100 day a year rider then plan on changing out your laces half way through the season.   We have been lucky so far and never had one break on the hill because any time they start to get frayed they break.  We mainly ride speed lace boots but we aren't that high on ourselves to say that's the way it should be.  Everyone is different.

All lacing systems have strengths and weaknesses.  It’s up to you to figure out what will work the best.

K2 Thraxis BOA

If you have the money, buy them. Or if you get them on sale, buy them. Def mos comfy boot ever. def made for a free-rider or speed demon, however, I just loosened them up to chillax and hit a few jumps n jibs. I hade a full day of POW on them, and my feet were soooo happy. I never had sore or cramped feet. the 3 BOAs really make for super easy adjusments. can't say enough about them, but they are really expensive.

my previous boots were burton rulers, and 32 lashed. the lashed only lasted on season. super light though, but not meant to last long, good thing I got them cheap. the rulers were cool, but I was not a big fan of the speed zone lacing. Maybe cause I got an early version of it, I am sure its better by now

Trying it out

1 of 2 people found the following review helpful
Just picked up a pair of these, will be riding them tonight for the first time. Coming from a set of the Burton Hail, I wanted something both stiffer and more responsive. While I have loved Hails (I have had 2 pairs) for the comfort and flex, it was time to upgrade in the response category to go with my other new equipment. I am riding a 2011 Burton Custom Flying-V with 2010 CO2 est bindings, and have been feeling like I can't take full advantage of the stiffer binding if my boot is flexing and sloppy inside it!
Try-on impression: The only boot I can remember putting my foot into with a stiffer feel was a Burton Driver X! In this same sitting I had tried on a Rome Folsom, and that boot was MUCH softer than I expected after reading about it on this site. Needless to say, the Thraxis was much more of what I had in mind when I went into the store even though it was not even on my radar at the time. The liner in the Rome Folsom is the most comfortable I have ever put on, so the K2 was almost losing points before my foot was all the way in! (K2's liners do exactly what they should without you noticing, but the Folsom was like a tempurpedic mattress wrapping my foot) Anyhow, once I started to crank down the internal ankle boa, I was pretty much hooked. An easy, fluid, and functional way to address heel hold without having to unlace any other portion of the boot is genius! Having separate upper and lower adjustment boas works well and is easy, but if the boot had a regular lace it would still be fine with me. I assume that is what the T1 is for, but there were none available for the price I got these at... I will update with riding impressions after a day or 2 in them!
