The Fizik Terra Artica GTX is an all-terrain, insulated winter mountain bike and gravel shoe designed to protect your feet during wet, freezing, or muddy off-road excursions. As a modernized and upgraded version of the classic Artica X5, it integrates a premium GORE-TEX membrane with a tactical micro-adjustable enclosure system.

Key Technical Specifications

• GORE-TEX Insulation:
  Features a fully waterproof and breathable GORE-TEX Koala insulated membrane (with select variants offering the PFAS-free Cirrus XT membrane) to completely block external standing water while allowing sweat vapor to escape.
• Thermal Core:
  Lined with an ultra-soft brushed fleece layer that traps body heat, ensuring warm toes during extended, low-temperature off-road rides.
• Dual-Closure Layout:
  Combines a secure, robust upper ankle Velcro strap for a locked-in ankle feel with a lower L6 BOA dial for precise, micro-adjustable tensioning across the midfoot.
• X5 Outsole Architecture:
  Upgraded carbon-reinforced nylon midsole with a stiffness index of 5, wrapped entirely in high-traction rubber treads. Includes removable toe studs for enhanced grip when hiking on slick, snowy mud.
• Rugged Materials:
  The exterior features a high-density, easy-to-clean polyurethane (PU) upper paired with high-abrasion Ripstop fabric zones to deflect trail debris and branch scrapes.
• Cleat Interface:
  Standard 2-bolt mountain bike style cleat box for compatibility with a wide range of MTB pedals.

Whether you're tackling icy trails or muddy gravel paths, the Fizik Terra Artica GTX is crafted to keep you warm, dry, and secure, no matter the conditions.
