Materials and technology

• Active3D™: thermoformed closed-cell foam fabric — reduces pressure and abrasions from rigid elements, waterproof, does not absorb sweat, easy to clean, with external hook-and-loop layers and formable properties for targeted shaping.
• BOA® Fit System: dial-and-lace micro-adjustable system for fast, repeatable, precision fit and progressive control of foot lifting.
• Stiffening: flat orthopedic stays positioned to support the structure where required.
• Paddings: 3D relief supports (EVA or foam) to relieve rigid elements and ensure skin comfort.

How to adjust BOA® Fit System
Attach the BOA® component to the shoe or designated anchor, turn the dial to tension the lace and increase dorsiflexion as required. Use micro-adjustments for optimal therapeutic effect and patient comfort.
