BOA®

 

Quick, precise closure — micro-adjustable fit you can fine-tune in seconds.

The BOA® Fit System is used on selected AKU models to deliver a fast, effortless, precision fit. Instead of tying knots, a micro-adjustable dial tightens a super-strong lace through low-friction guides — creating a secure, even closure. It’s especially useful when conditions are cold, wet, or you need adjustments on the move.

  • Micro-adjustable precision: small fit changes without re-tying.
  • Fast on/off: tighten or release quickly — even with gloves.
  • No loose laces: reduces snag risk in brush and rough terrain.
What this means for you

A more consistent, dialled-in fit through the day — easier to adjust for uphill, downhill, swelling, or changing socks — without stopping to re-lace.
Precision dial closure used on selected AKU models where quick adjustment and secure fit matter most.
What is the BOA® Fit System?
 

The BOA® Fit System offers a micro-adjustable precision fit designed for demanding conditions. The patented system consists of three integral parts: a micro-adjustable dial, a lightweight, super-strong lace, and low-friction lace guides. Together, they create a secure closure that’s quick to fine-tune and easy to release.
The three BOA® components (and what they do)
 
1) Dial
Fine-tunes fit with precision — quick, repeatable micro-adjustments for a secure feel.
2) Lace
A lightweight, super-strong lace configured for precision and durability in demanding use.
3) Guides
Low-friction lace guides replace traditional eyelets, helping distribute closure more evenly and smoothly.
How to use BOA® (push, turn, pull)
 
  1. Push the dial in to engage.
  2. Turn to tighten — small turns = small changes in fit.
  3. Pull the dial out to release (then open the upper as needed).
Fit tip

For best comfort, aim for a secure heel with comfortable toe room. Use micro-adjustments through the day as feet warm up or swell.
Watch: how BOA® dials in fit
 
What you’ll learn in 60 seconds
  • Micro-adjustments: how small turns fine-tune fit.
  • Fast release: how to loosen quickly when stopping or changing socks.
  • On-the-move comfort: why precise closure helps stability and control.
 
Tip: Make one or two clicks/turns at a time — it’s designed for small, precise changes rather than big jumps.
Why BOA® matters in real use
 
  • Better control through the step: consistent closure helps reduce unwanted foot movement inside the boot.
  • Faster adjustments: tighten or release in seconds — useful in cold weather, wet ground, or when stopping briefly.
  • Less snag risk: no loose lace ends to catch on brush or undergrowth.
Best use cases

Fast adjustments on the move, glove-friendly closure, and secure fit for mixed terrain use — especially where you’d normally be stopping to re-tie laces.
Care (keep the dial smooth and reliable)
 

BOA® systems are built for hard use, but like any closure they perform best when kept clear of packed grit and dried correctly.

1
Rinse after heavy mud/sand
If the dial feels gritty, rinse with clean water and gently work the dial (engage/turn/release) to help clear debris.
2
Dry naturally
Dry away from direct heat (no radiators/fires). Direct heat can stress materials and reduce long-term comfort.
3
Check lace routing occasionally
If you notice uneven pressure, check the lace sits correctly through the guides and that the upper isn’t caught or folded.
If something breaks

BOA® systems are designed to be serviceable. Replacement parts and repair guides are available via BOA support (dial/lace kits vary by model).

BOA® FAQs
 
How do I tighten and loosen BOA®?
Push the dial to engage, turn to tighten, and pull the dial out to release. Make small adjustments — one or two turns at a time — for best comfort.
Will BOA® loosen on its own?
In normal use it should hold securely. If you notice slippage, check the dial is fully engaged (pushed in) and that the lace is routed cleanly through the guides. If the fit feels inconsistent, the issue is often lace routing or packed grit — a quick rinse can help.
My dial feels stiff or gritty — what should I do?
Rinse with clean water to clear mud/sand, then gently work the dial (engage/turn/release). Let the boot dry naturally away from direct heat. Avoid forcing the dial if it’s packed with grit — clean first.
Can BOA® be repaired if something breaks?
Often, yes. BOA provides replacement parts and step-by-step repair guides for many dial systems. Parts vary by model/dial type — if you share your AKU model name, we can help you identify the right approach.
Is BOA® better than traditional laces?
It’s different rather than “better” for everyone. BOA excels when you want quick micro-adjustments, glove-friendly closure, and no loose lace ends. Traditional laces can offer more custom patterning across many eyelets. If you tell us your use case, we’ll recommend the best option.
Will BOA® change sizing or fit compared to laces?
The boot last and volume matter most, but BOA can feel more “even” and secure because closure is consistent. Choose your normal AKU size unless the product page advises otherwise. If you’re between sizes or using thick socks, we can help.
