Union Atlas Step On Bindings Review

Overall, I found the Union Atlas Step On to be light-feeling, fairly responsive at slower speeds and particularly capable for carving. They delivered a direct connection to the board and handled more aggressive riding well, without feeling excessively stiff or demanding.

However, like the other Step On bindings I’ve ridden, they didn’t give me the same natural board feel or freedom to manipulate the board that I get from a good pair of traditional two-strap bindings.

They also didn’t feel dramatically different from the Burton or Flux Step On bindings I’ve tested. I didn’t feel they were noticeably/significantly better or worse overall - just another variation on a system I’m still not completely sold on.

As always with Step On bindings, there’s an important testing caveat. I couldn’t use my normal control boots, so it was harder to isolate how much of the feel came from the bindings and how much came from the Step On boots. The boot and bindings work together much more as one system than they do with traditional bindings

In addition, the boots had to be different than those I used with my control setup, so the results of this test aren’t as accurate as they would be with our testing of bindings that are compatible with our test boots.

In this review I will take a look at the Atlas Step On as all-mountain snowboard bindings.

As per tradition here at SnowboardingProfiles.com I will give the Atlas Step On a score out of 100 (based on several factors) and see how they compare with other all-mountain bindings.

Specs

Who are the Atlas Step On Most Suited To?

The Union Atlas Step On are best suited to riders who already like the Step-On system or think they might like it - and want a supportive, mid-stiff setup with good carving performance being a priority.

They should work particularly well for riders who value a direct and precise connection versus a freer, more surfy or highly tweakable feeling. They had good support, drive and strength for riding with speed and laying into carves, but weren’t so stiff that they felt like an ultra-aggressive hard charging specialist binding or anything.

I see them working best with medium to mid-stiff all-mountain, aggressive-all-mountain and freeride boards. Based on how they felt to me, I would pair them with boards in roughly the 5/10 to 8/10 flex range and even more ideally in the 6/10 to 7/10 flex range.

Riders who prioritize board feel and/or plush shock absorption will likely prefer other options. And, naturally, they only make sense for someone who either already owns compatible Step On boots or are prepared to get them.

Test/review details for the Atlas Step On

O.k. let’s take a more detailed look at what the Atlas Step On are capable of.

Test Limitations

Comparing the Atlas Step On directly against traditional bindings wasn’t as clean as it normally is.

With regular bindings, I typically use the same boots, board and binding setup to create a reliable control setup. With Step On bindings, I have to use Step On boots, and it’s more difficult to make comparisons of the test bindings (in this case the Atlas Step On) versus my control bindings when you have to change the boots – it makes it harder to know how much of the differences felt is because of the bindings and how much is because of the boots.

Flex

In Hand

The Atlas Step On’s highback had a moderate amount of twist flex. Not super flexy but not super stiff either.

I rated its highback twist at around 6/10. It had a little more flex on the lateral side than the medial side, but the difference wasn’t especially dramatic.

That put it flexier than the much stiffer Malavita (control bindings) and Source Pro TH highbacks, as well as below the Atlas Pro Step On and Ultra. It was slightly softer than the Contact and noticeably stiffer than the Neo and Flite Pro.

Pulling directly back on the highback produced a stiffer result. There was only very subtle movement, which put its pullback flex at around 8/10. That was similar to the Contact and Flite Pro, below the Atlas Pro Step On and Ultra, and noticeably stiffer than the Neo.

Naturally, being Step Ons, which don’t have straps, there were no ankle or toe straps to assess.

On Snow

On snow, the complete setup felt around a 7/10 overall.

They were clearly supportive and more powerful than the average bindings, but they didn’t feel brutally stiff or unforgiving or anything.

Again, it was difficult to establish precisely how much of that feel came from the bindings and how much came from the boots. But as a complete system, they felt right around that 7/10 mark - enough support for harder carving without becoming too much work when I slowed things down.

Carving and Response

Slow-Speed Agility

The Atlas Step On were reasonably easy to turn at slower speeds and didn’t feel excessively rigid. Compared with my control bindings, they felt only mildly more difficult to turn with at slower speeds.

My general impression was that they were responsive enough at slower speeds, but their strongest quality wasn’t playful, effortless agility. They felt more at home when I gave them a little more speed and pressure.

Carving

Carving was one of their stronger areas, for sure. They felt immediately better for carving than my control bindings and better than any of the traditional Union bindings I had ridden the previous day.

The direct boot-to-binding connection likely helped transmit pressure quickly as carving performance is something that I have found to be really good on all the step on bindings I have tested. The mid-stiff feel also helped to give me enough support to lean into an edge without the setup folding or becoming vague.

I didn’t get perfect conditions for making a definitive comparison, so I stopped short of giving them a full 5/5. But they felt powerful and dependable when I was able to get onto cleaner snow and properly load up a turn.

Board Feel and Butterability

Board feel was decent but not a major strength. With Step Ons, the boots are connected to the highback and locked into specific connection points at the toes.

I’ve found that this locked in feeling with step on bindings makes it more difficult to manipulate the board’s flex and the Atlas Step On weren’t an exception to this.

They didn’t feel completely dead or disconnected or anything though. I could still feel what the board was doing and move it around reasonably well. But I didn’t get the same natural, fluid feeling that I get from bindings that allow the boot and straps to flex together more progressively.

Riders who preferred a direct and locked-in connection might have liked this more than I did. Personally, I preferred having a little more freedom to work against the straps and subtly change how pressure is distributed.

Shock Absorption

On inspection, I felt a good amount of cushioning under the toe and midfoot. The heel area, however, felt considerably firmer.

On snow, they didn’t feel as damp as the Union Neo or Ultra. They also felt a little less shock absorbing than my control bindings.

I wouldn’t say they were harsh or anything, and I didn’t experience any serious discomfort from chatter or impact. But also not high-end shock absorbing.

Pop and Ollie Power

Pop and ollie power felt good, without being exceptional.

The direct connection and supportive flex gave me something solid to pull against when loading up an ollie. They didn’t feel springy in an exaggerated way, but they transferred energy efficiently and didn’t hold me back.

There was enough response for boosting off natural features and getting good energy back out of the board. They were what I would call normal in this respect. I find the board has a greater effect on this, but bindings can make some difference.

Adjustability

Adjustability was fairly limited, which was unsurprising for a Step On binding. There was no adjustable heel cup*, ankle strap, toe strap or heel ramp. The highback couldn’t be rotated either.

*Adjustable heel cups are synonymous with Union bindings, but it’s not surprising that they haven’t worked out a way to incorporate that into a Step On binding yet (if it’s even possible), with this being just the 2^nd iteration of a Step On binding for Union, given how the boots are locked into the highback and have to line up with the toe locks.

They do have gas-pedal extension, which helps with boot centering and they use Union’s Universal Disc, compatible with standard insert patterns and the Channel.

Forward lean could be adjusted using a two-stage system. However, it required a screwdriver and swapping the integrated pieces rather than being tool-free. Not a deal breaker as most would find a position and stick with it, but just makes it a bit harder/longer if you’re wanting to experiment with different amounts of lean.

Overall, they provided the essential setup options, but weren’t overly adjustable.

Comfort and Ankle Support

Nothing felt uncomfortable, but nothing stood out as especially plush either. Naturally without an  ankle-strap or toe-strap there were no strap pressure points, which removed two potential sources of discomfort.

The highback didn’t have any padding, but I didn’t get any calf bite. The firmer heel cushioning prevented them from feeling particularly luxurious but all round, I didn’t experience any discomfort from them while riding.

Ankle support was a little harder to determine. They’re not directly comparable with a normal binding, being that there’s no ankle strap providing independent support. Instead, the ankle support relies predominantly (maybe entirely?) from the boot and the way it locked into the binding.

The setup felt secure enough, but anyone evaluating ankle support would also need to look closely at the specific Step On boot they planned to use.

Entry and Exit

I’ve tested Step On bindings a good few times now, but I still find the process a little awkward, though I freely admitted that I could be a slightly awkward myself!

It became better and more fluid with some practice, but I haven’t reached the point yet where stepping in and out felt completely automatic. I imagine getting day to day, consistent repetitions would help a lot. But a warning that it may not be something you’ll be comfortable and smooth with off the bat.

I have heard from others who use Step On bindings regularly that they generally find it fast and easy once the movements became familiar.

The potential was clearly there. Once properly aligned, getting connected required very little effort, and there were no straps to move out of the way or ratchets to tighten.

My personal experience just hadn’t reached the effortless stage yet.

Score Breakdown and Final Verdict

Check out the breakdown of the score in the table below.

The Atlas Step On felt light, supportive and particularly strong for carving.

Their mid-stiff flex provided a good balance between power and usability. They handled faster, more committed riding well while remaining decent at slower speeds.

Board feel, adjustability and shock absorption weren’t as strong as their carving abilities. Not terrible or anything, but they didn’t provide high-end natural board manipulation, customization or dampness.

Ultimately, they felt pretty similar to other Step On setups of a similar flex, that I’ve ridden. I didn’t think they were noticeably better or worse.

For someone who was already sold on Step On and wanted a capable, mid-stiff all-mountain binding with strong carving performance, the Atlas Step On makes plenty of sense. And to be fair they look pretty sick! (which of course is very subjective – beauty in the eye of the beholder and all that)
