When you're running on rugged, unpredictable terrain, fit is everything. A secure, stable shoe can mean the difference between a powerful stride and a rolled ankle. Two standout technologies used by Kailas trail running shoes are the BOA® Fit System and Kailas AWS (Adjust Whole Sole) System. But what are they exactly? And how do they compare?
Let’s break it down.
🌀 BOA® Fit System: Precision at Your Fingertips
The BOA® Fit System is a globally recognized lacing innovation that replaces traditional laces with a dial-based mechanism, offering:
Micro-adjustability: Fine-tune your fit with a simple turn of the dial — even mid-run.
Even Pressure Distribution: Reduces pressure points across the foot.
Quick Lock-In: No tying, no loosening — just twist and go.
Durability: Tested to withstand extreme conditions.
You’ll find the BOA® system on models like the Kailas Fuga DU and Fuga EX 3, designed for trail runners who want fast, responsive fit control.
⚙️ Kailas AWS 3.0 System: Total Sole Control
Unique to Kailas, the Adjust Whole Sole (AWS) System 3.0 is a dual-zone tightening system. It's engineered specifically for the EX3 series, delivering a tailored fit from toe to heel:
Front Zone Control: Relieves pressure on toes, especially during downhill runs.
Mid & Heel Zone: Ensures snug heel lock and arch support for stability.
Wrap-Around Fit: Helps minimize foot slippage and improves agility on technical terrain.
Together with BOA, the AWS 3.0 creates a double locking mechanism — making the Fuga EX 3 one of the most secure trail shoes in its class.
đź“Ś Final Thoughts
For serious trail runners, fit is more than comfort — it’s performance and safety. The BOA® and AWS systems offer next-level lockdown and control, so you can focus on the trail ahead, not your laces.
