Helios SR is the minimalist shoe by La Sportiva dedicated to the world of sky races and vertical competitions. Every detail has been thought to keep weight at a minimum without compromising the structural and protective features fundamental for racing. When the trails are unpredictable, the Helios SR will make sure that you are prepared for what lies ahead.  This performance trail shoe features a wave pattern outsole for outstanding flexibility, with a rigid rubber compound in the heel for increased traction and durability over rocky terrain.  A snug fitting upper with quick draining and moisture regulating properties keeps your feet comfortable and protected against the elements.


  • Morpho Dynamic EVA is a soft, highly compressive foam that deforms upon impact to dissipate impact forces, creating a smooth stable and cushioned ride.
  • Endurance Platform EVA Insert is a support structure between the midsole and outsole that dissipates impact forces and provides protection over rocky terrain.


  • FriXion XT is a full length versatile sticky compound designed for technical and rocky terrain.
  • VA Wave is an outsole pattern with outstanding flexibility and responsiveness, offering a smooth ride over a variety of surfaces.


  • HyDrain Nylon Mesh allows for quick drainage while keeping out debris.
  • Wicking EVA Air Mesh throughout the upper keeps feet cool and ventilated while fending off moisture.
  • Poly Grid upper regulates temperature and drains moisture to keep your feet cool and comfortable.
  • Lacing Harness is a thermoplastic unit extending from the lacing eyelets to the midsole for a snug, secure fit.
