  • With a medium flex index, Lange SX 120 ski boots provide the responsive power transfer preferred by aggressive intermediate skiers
  • Roomy, 102mm footbeds offer a comfortable fit and can accommodate wide feet
  • Uniform-density plastic shells ensure highly efficient power transfer, smooth flex and finely-tuned responsiveness, even in frigid temperatures
  • Shells are designed to create a centered, balanced stance on rockered skis to increase efficiency of technique and reduce fatigue
  • Liners comfortably contour your feet and precisely match the internal shape of the shell to create instant responsiveness, and they may be custom molded using a heat treatment
  • 1-piece toe boxes and tongues eliminate seams and overlaps in the tongue attachment area, reducing pressure points at the instep and top of the toes
  • Specially designed insteps provide an excellent fit at the midfoot, resulting in increased circulation and greater warmth
  • Saddle-stitched seams help reduce hotspots
  • Rubber soles offer excellent grip
