Secure lace containment

As of 2017, there were more than two million pairs of safety footwear equipped with the Boa Fit System across Europe. 

For workers across construction, manufacturing, mining, oil and gas, transport, and more, the Boa Fit System lets users dial in a secure fit for enduring comfort that stays consistent and true. The Boa Fit System is made up of three integral parts: a micro-adjustable dial for a precision fit, lightweight and super strong laces, and low-friction lace guides to ensure a smooth closure. Whether removing gear at the door or acting quickly in a dangerous situation, Boa makes it easy to get shoes off (and back on) in a hurry and increases safety while working around machinery and hazards with secure lace containment that never comes untied.

From Boa’s proprietary textile, to aircraft-grade stainless steel permeated with abrasion-resistant nylon, Boa laces are extremely strong, built to withstand 10 times more tension, than they would require to close a shoe comfortably. While only 6.8 kg (66,7 Newton) of usable tension is needed to close mid-cut footwear, yet the Boa Fit System CS3 lace is tested to allow for over 70 kg (686 Newton) of tension before a lace would ever break. Boa CS1 laces are also designed to withstand lace fatigue over time and tested to last over eight million steps or approximately 6437 km. 

Designed to reduce contamination by shedding ice, dirt, oil, and other elements, the Boa® Fit System works hard so the user can stay focused and confident in any environment. The system is tested for impact and durability. When operating as one unit (Dial-Lace-and-Guides) the breaking force of the Boa® Fit System can withstand up to over 190 kg (1864 Newton) in its high power system (H3).

Boa offers varying systems to address a variety of tension demands, including different dial size and grips, to meet specific application and product needs. The Boa Fit System in workwear consists of three platforms: L6, M4, and H3+ with Boa’s Coiler technology.
