We know you’ve felt it: the pure focus and exhilaration of being totally immersed in what you love. But when your gear doesn’t fit how you want, it pulls you out of the moment and off your game.

Boa makes it easy to dial in the perfect fit, bringing you closer to your equipment for improved agility, response, and control. Instant micro-adjustments provide enduring precision and a custom fit that improves performance - anytime, anywhere. When your gear disappears from thought, all that’s left is the moment.

The Boa
Fit System.

While the Boa Fit System is custom built for each unique product and use case, they all contain three integral parts: a micro-adjustable dial, super-strong lightweight laces, and low friction lace guides. Each configuration is engineered to optimize fit and provide precision, adaptability, and control.

Boa Laces

The workhorse of the Boa Fit System, our laces routinely tolerate the toughest tests.
Lightweight, super-strong laces, expertly configured for comfort and performance.

Boa Guides

Our lace guides replace traditional eyelets, and the deficiencies that come with them.
We designed our lace guides to optimize the Boa Fit System by minimizing friction and improving fit in a way that wasn’t possible before.

Boa Dials

Tuned and tested to the highest standards, Boa dials provide the ultimate fit experience so you can focus on what matters most.
Varying in size, design, and interface, the dial fine tunes fit with precision, allows for quick release, and never settles on performance.

How it works.

The Boa Fit System features three
user interfaces, purpose-built
to optimize the fit experience. 

With instant, single-handed fine tuning as precise as 1mm, you can easily adjust for comfort or a more targeted performance without ever losing focus. And once dialed in, the Boa Fit System stays that way. At the mountain, on the course, or on the job, Boa gives you a secure fit that makes it easy to get your gear on and off quickly no matter the conditions.

There are three series within the Boa Fit System for different applications: L-SERIES, M-SERIES,
and H-SERIES. 


Lightweight, lower tension, for low-cut footwear and similarly sized products that demand precision.

Meant for the agile athlete who needs meticulous adjustment capabilities for ultimate comfort, adaptability, and overall performance.

Boa L Series


Multifaceted, with maximum versatility to withstand variable conditions.

With its fast wind system, the M-SERIES has increased lace tension, speed, and dexterity. The M-SERIES excels in ice, dirt, oil, and other challenging environments and we designed it to be easily adjusted even with gloves on. The mid-capacity dial combines durability and closure strength to withstand intense force and impact, without sacrificing fit. 

Boa M Series


High capacity, high power, engineered for heavier materials and high-cut footwear.

The H-SERIES is built for thicker, stiffer applications, deftly handling layers, liners, and insulation on snowboard boots and other large, difficult-to-close equipment. The dial engages a geared system creating maximum lace tension, security, and support for our most powerful fit system yet.
