Hello and welcome to my Flux SR review.
In this review I will take a look at the SR as freeride snowboard bindings.
As per tradition here at SnowboardingProfiles.com I will give the SR a score out of 100 (based on several factors) and see how they compare with other freeride bindings.
Note: The Flux SR are quite soft flexing and I wouldn't normally rate these in the freeride category. This category typically has stiffer bindings, but we decided to include the SR here since Flux describes them essentially as "powder" bindings. However, since they don't fit nicely into any of our categories, they don't rate as well as they might if there was a dedicated "surfy powder" category" or something like that.

Who are the SR Most Suited To?
The SR are best suited to riders who want to get off groomer and into some fresh snow, but would prefer a softer feel from their bindings, for a more surfy feel - and don't mind sacrificing some carving power when the snow hasn't been falling and they're confined to the groomers (or have other bindings/another setup for those days). But would work well for cruisy groomer days.
While they are pretty easy turning I wouldn't go as far as to say that they're good for beginners, but low-end intermediate and up should be fine with these if it's the type of binding they're looking for.
Best matched to boards in the 3/10 to 6/10 flex range and even better for those in the 4/10 to 5/10 flex range.
Test/review details for the SR
O.k. let’s take a more detailed look at what the SR are capable of.
Demo Info
Binding: Flux SR 2026, M
Date: March 31, 2025
Responsiveness
It felt pretty even between carving support/power and slow speed sharp turns, with a bit of a preference towards slower speed sharp turns.
Board Feel/Butterability
Felt ok without being great to me. Not quite as good as the Flux XW (which I also rode that day) felt in this regard. Not sure the reason for it, but I felt the board feel was just a little worse here.
Pop/Ollie Power
Felt pretty much normal. Not typically a lot of variance between bindings here as most of it comes from the board, IMO, but bindings can make a small difference. These were pretty much neutral.
Adjustability
Heel Cup: No
Stance Width: Yes – can run disc either way, and has 3 positions for the screws for good micro adjustability.
Highback Lean: No
Ankle Strap Position: Yes – 2 positions and this is also tool-less which it isn't on most bindings (ankle strap length is more often than not tool-less, but for those bindings that you can change the position of the ankle strap on, it typically requires a tool).
Toe Strap Position: Yes – 2 positions
Ankle and toe strap length: Yes and tool-less
Gas pedal/toe ramp extension: Yes
Highback Rotation: Yes – and now 5 different positions, which is heaps. And this is also tool-less, which I don't think I've seen before for highback rotation, so that's pretty cool.
Compatible with: 2 x 4 | 4 x 4 | The Channel
Shock Absorption
Not what Flux are known for and while I did think these had a little more than some other Flux bindings, still not a lot of shock absorption going on here.
Entry/Exit
Ankle/Toe Ratchet Smoothness: Fairly smooth. Not smoothest ever, but as smooth as you need it, IMO.
Process: Typical 2 strap binding process.
Found it easy to strap in and de-strap on the move - nothing special but nothing that detracted from the entry/exit experience either.
Comfort
Overall nice and comfortable bindings that conformed to my boots like a glove to a hand.
Ankle Strap: The SR uses Flux's new Cloud Strap (also featured on the DS and on the new CX). It felt real comfy. It’s got this springy foam kind of feel to it. Not like the old material straps. It’s kind of spongy but springy sponge, if that makes sense. Lots of rebound to it. There’s a plastic frame that sits over the strap – though when I say plastic, not really sure what it's made from. It has a rubbery texture to it – so I’m not sure if it’s plastic or latex or rubber something.
Whatever it is that makes this ankle strap work, it works really well - conforms really nicely and feels snug and no pressure points. One of my favorite ankle straps now.
Toe Strap: Felt nice and flexy and conformed to the toe of my boots really well. Has the same rubber-ish texture as the frame over the ankle strap. I typically like Flux's ankle straps and this one was no exception.
Canted Footbed: No.
Padded Footbed: There’s actually a little padding in the middle (and I say actually, because Flux bindings often have next to nothing). Kind of token, but it likely helps dampen vibrations a little bit. I’d say more about chatter reduction than shock absorption, since it’s in the mid-foot spot, which isn’t going to take a lot of impact.
Highback: A little right at the bottom – but no where else. But main thing, comfort-wise, is that there was no calf bite or other pressure points.
Ankle Support
Typical of Flux bindings, they had really good ankle support. I would say not as ankle supportive as some of their bindings, which I would guess was on purpose, to given them a more surfy feel. But still really good ankle support.

| Entry/Exit | 4 | 4/5 |
| TOTAL (after normalizing): | 81.6/100 |
The SR are bindings that are quite unique in the sense that they're designed to be freeride oriented, but are softer flexing than most that we'd put in the freeride category. An outlier of sorts.
So while they may not rank very high in this category, they are still very good bindings, just don't expect them to be hard carving beasts or anything. They do better with more moderate speeds.
They are high quality, IMO and true to Flux offer really good ankle support, adjustability and comfort (even in spite of minimal shock/chatter absorption). But they are quite a niche offering, which is perhaps why their availability is pretty scarce.

Hi Nate,
It looks like you have ridden Flux in both M and L in size 10 boots. Can you comment on their sizing?
I have 9.5US Ride Infuses, which would be closer to a 10 for most brands. I prefer more heel over hang than toe. The boots fit well in Medium Unions with the heelcup pulled all the way back.
I am considering the DS but not sure if I should do M or L
Hi Jared
Thanks for your message.
Can you clarify if you mean Ride Fuse or Vans Insfuse? Either way, I think they’d likely fit in an M in a 9.5. I had no issues fitting my Vans Aura 10 in the M, though they are relatively low profile both in terms of length and in terms of the height of the toe box end. The Vans Infuses that I’ve measured are just as low profile as the Aura – though with a little bit of a higher toe box, but I think they’d still fit in a medium. I haven’t measured a Ride Fuse, so I’m not sure specifically, but most ride boots I’ve measured have been quite low profile (in saying that it does depend on the individual model sometimes), so I would suspect that the 9.5 Fuse would be fine.
However, given that you like more overhang on your heel, I think Large is probably the way to go. I’ve never had any issues in Large, with size 10s. With 9.5s, it’s a little smaller, so couldn’t say for sure, but I think you’d be fine, particularly if you want that extra heel overhang.
Hope this helps
Thank you Nate. Yes, I meant the Ride Fuse. With the spine of the boot against a wall, it measures 31.1cm but the sole itself is about a half cm shorter.
Fixed heel loop bindings are always tricky to size. K2’s in large fit my boots perfectly. With Burton the mediums were always a touch small and larges too big.
Hi Jared
That is really quite long for a 9.5 (though our measuring techniques might vary). Still I think Large is the way to go even more so now. Yeah, definitely easier to get that boot centering with an adjustable heel loop for sure.
