K2 Sonic 2019-2020 Snowboard Bindings Review

  • Sizes: M, L, XL
  • Flex: 3
  • Entry System: Classic
  • Price: £135 / €160

Comfort and ease are the buzzwords when it comes to the K2 Sonic, a soft flexing binding aimed at riders who are looking to progress their riding. If you’re searching for something that will perform well across the board, with a low price point then the Sonic might just be the binder for you.

A 3D injected ankle strap is made to fit around the shape of you boot and is slightly padded to increase your comfort for those long days on the hill. Toe straps are minimalist in design, but maximum in support, they sit round the front of your boots and lock you down.

“Foam footbeds work to gobble up some of that chatter as you’re riding through crud”

Foam footbeds work to gobble up some of that chatter as you’re riding through crud and take a bit of the sting out of impact as you’re landing. They’re also made to sit at a slight angle to offer more support to the outside of your foot, this will allow your leg to be in a more natural position.

The Sonic boasts totally tool-less adjustability, so you’re able to ensure you’re getting the right fit every time. If you’re still finding your feet on your board, it’s one less thing for you to have to faff around with meaning you can focus more on your riding.

The softer flex is really handy for progression, as it’s not going to punish you for every little wobble or mistake. It’s a confidence-boosting, long-lasting, piece of tech that’ll stand up to the elements.

Tester’s Verdict

Paul WoolProfessor

“Top line, the K2 Sonic is a great value bit of kit for a beginner, or if you happen to be in the market for a super soft binding that supports where it’s essential and provides a comfortable ride. Lets not ignore that price tag either, that’s a good deal.

I decided to go left field with the Sonics; I normally like a stiff responsive binding for aggressive riding. I’ve also been snowboarding for over 20 years, so I wouldn’t class myself as a beginner either.

“A perfect set of bindings for beginners, solid and comfortable with a great price”

In your hand, they look decent; light and well made, not brimming with gimmicks and tech nonsense. Fully conscience of the low price I strapped in with an open mind but was pleasantly surprised. My boot fitted in the highback and chassis comfortably, the straps and buckles both felt really solid. Other than the natural flex, there was no play from my boots, the straps didn’t come loose or get stuck either. All the tool free adjustments worked well, I didn’t have a melt down, or pull a fingernail off trying to adjust the straps.

I rode these bindings on a short Salomon Sick Stick in order to really get a loose surfy feel, with tons of upper body movement. It took a bit of getting used to but I found the experience enlightening, with the short fat board and flexy bindings allowing for exceptionally tight and nimble turns. Slashing, buttering, jibbing was all fantastic. Tweaking out grabs and correcting sketchy landings was a breeze – tons of fun.

But man, do these things flex? The highbacks move laterally, vertically, every-which-way, which would be great for the slower stress-filled turns of a beginner, but be aware at speed your body weight can get easily misplaced. It’s pretty easy to get out of control and slide out. The flex definitely makes you feel chatter and vibrations a lot more. But overall the base is really good, I can’t argue with the EVA material, it sucked up landings really well, and kept my feet in tune with the board underneath.

Definitely a perfect set of bindings for beginners, solid and comfortable at a great price.”
