Built for performance – with USB charging…

A performance boot for the resort with a moderate flex, the new Spyre 100 offers the best of both worlds. The 100 flex facilitates powerful skiing when required yet is soft enough for finesse turning in variable conditions. Combined with the LuxFit PRO liners with optional USB rechargeable Thermic technology, the Spyre 100 is fully customizable for a precision fit. 

Pretty much a radiator for your feet

Three heat settings, the heat controls sit just above the shell on the lateral part of the boot for easy access, even while skiing. Rechargeable via the secure yet easily accessed micro-USB port, the lightweight lithium-ion batteries provide up to 19 hours of heat.

The best bits...

  • Strategically combined heat-mouldable foam and traditional foam liner
  • Replaceable Outsoles with Dual-injected soft and hard Thermo Plastic Urethane (TPU) for secure footing and increased life of the boots
  • Power Wedge with removable spoiler for adjustable forward lean angle from 12 to 14 degrees.
  • Dual sided cuff alignment for +/-2 degrees of cuff adjustment
  • Energy Interlock - rivet-free technology that integrates the cuff and shell, putting less stress on the boot's material and produces a smoother, progressive flex
  • A rear co-injected Powerfuse Spyne - "Y" shaped support that adds strength and power to the Energy Interlock to maximize fore/aft flex efficiency and lateral stiffness
  • New removable and interchangeable ISO 9523 alpine rockered soles collaboratively designed to work with Marker's Grip Walk binding system for better grip and added comfort 
  • Moulded/Lasted Design
  • Foam Lower
  • Strategically placed EVA Foam
  • Mouldable Asymmetric Tongue
