A performance ski boot for the resort with a moderate flex, the new K2 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.


  • Lux Fit Pro liner - Strategically combined heat-mouldable foam and traditional foam liner
  • Power fuse SpYne: A rear co-injected "Y" shaped support that adds strength and power to the Energy Interlock in order to maximise fore/aft flex efficiency and lateral stiffness for responsiveness in every type of terrain
  • Power Wedge: A removable spoiler for adjustable forward lean angle from 12 to 14 degrees
  • Energy Interlock: a rivet free technology that locks the cuff and lower shell giving the boot a smooth linear flex
  • Dual Cuff Alignment - Adjusts the cuff +/- 2 degrees on the medial and lateral so your cuff and leg work together


  • 102mm Last Width
  • 100 Flex
  • Sizes: 22.5 to 27.5 (full half sizes only)
  • Replaceable outsoles - upgradeable to Marker Grip Walk for use with compatible bindings
  • MFG Part Number: S171903001
