  • 72 / 100 by RunRepeat • Ilsuk Han • Level 2 expert

    I liked the Helios SR for their lightness and flexibility which was conducive for "natural" running while at the same time providing decent cushion and responsiveness.

  • 87 / 100 by Trail Runner Buddy • Buddy Jones • Level 1 expert

    Shoes are super comfortable. Feeling pretty light. Liking the really low drop on them. They've been really good on the sharp, little rocks that I've encountered here and there with the rock plate.

  • 86 / 100 by Must Love Jogs • Must Love Jogs • Level 3 expert

    It’s actually rather perfect – like putting on a slipper to hit the trails – but not just any slipper – a slipper with some badass tread. 

  • 83 / 100 by Neil Bryant • Neil Bryant • Level 3 expert

    Although I will be wearing this shoe pretty much exclusively on technical Alpine terrain, I feel that this would be best suited to relatively well maintained trail, with not too many technical sections.

  • 82 / 100 by Tri Radar • Tri Radar • Level 3 expert

    Pushing the pace is easy enough in these shoes although for longer runs or tougher terrain you may feel you need a shoe that is more rugged. 

  • 50 / 100 by Feed the Habit • Donald Buraglio • Level 3 expert

    La Sportiva’s Helios SR provides an outstanding combination of lightweight, minimalist construction with high performance and high durability for virtually any mountain running conditions.

  • 88 / 100 by Climbing • Julie Ellison • Level 1 expert

    Cover a light, zippy trailrunner in sticky rubber, and you get the Helios SR.

  • 85 / 100 by Runultra • Steve Diederich • Level 1 expert

    With the exception of the toe box issue I had, they are a really competent and well-made shoe that whist designed for mountain running are more than capable of carrying you in comfort over multiple terrains whilst technically performing at a high level.

  • 84 / 100 by The Long Run • Aaron Knight • Level 1 expert

    They are still super-light and responsive but the rock plate gives you more protection on rocky ground. 

  • 82 / 100 by On Two Feet • On Two Feet • Level 1 expert

    If there is a rock plate in there I don’t notice it and they feel much the same as the originals in that respect.

  • 80 / 100 by Stone Runner • Stone Runner • Level 1 expert

    They are the super much loved and mega light Helios SR with an inner type upper sock fit to ensure comfort and secure fit.

  • 77 / 100 by Walkhighlands • Peter Macfarlane • Level 1 expert

    The unusual look is good on rough ground, but better in dry conditions as although the tread pattern has deep ridges in it, they’re rounded so don’t bite very well.

Updates to La Sportiva Helios SR

  • La Sportiva brings to the fore an ultra-aggressive and strikingly lightweight trail shoe that can tackle technical terrains, rocky areas, steep inclines, or downhill bombs with aplomb in the Helios SR. As the SR stands for Sticky Rubber, La Sportiva uses a new compound in the Frixion XT to deliver an all-around traction that most trail runners would dearly love to have in their trail shoes. The shoe has enough stickiness that it can very well be a rock climbing footwear, instead of just a trail version.
  • The fully gusseted and stretchable upper keeps debris off while it continues to make breathability such a huge feature in this shoe. Because it adapts quite well to the runner’s foot, the upper accommodates different foot dimensions and eases off the constrictive feeling from a company that normally produces shoes that tends towards being narrow.
  • The signature part of the Helios SR is the wave pattern in the outsole, which adds more flexibility to the shoe and helps keep the weight of the shoe down despite the excellent cushioning and underfoot protection coming from a lightweight package.

La Sportiva Helios SR size and fit

The fit runs on the narrow side like most La Sportiva shoes. As mentioned, the decent stretch coming from the upper helps the Helios SR accommodate runners with slightly wider feet. It also eases off the constrictive feel if worn right out of the box. The volume and width of the toe box are just about enough for the runner to be comfortable. Available widths are the standard D for the men’s and B for the women’s. Sizing is a bit off since it is half a size smaller than regular measurement. Again, most of La Sportiva’s shoes are built this way. Sizes are from 6 to 15 for the men’s and 5 to 11 for the women’s.


Outsole

The outsole of the La Sportiva Helios SR is identified by the wave pattern. This is designed to add maximum flexibility as befitting of a lightweight shoe with minimalist tendencies. The lugs in the outsole are super aggressive and are covered by a new rubber compound in the Frixion XT that substantially increase its traction on a multitude of trail surfaces, even in wet conditions.


Midsole

La Sportiva uses a full-length Morpho Dynamic EVA for consistent cushioning and shock dispersal. An Endurance Platform EVA Insert works in the midfoot to provide torsional rigidity and a little arch support. While the shoe is without a rock protection plate, it relies on a flexible, compressed EVA in the forefoot to protect the foot from sharp objects on the trail.


Upper

The upper is largely made of the Hydrain Nylon Mesh for impressive durability and breathability. It has decent stretch to really mold itself to the runner’s foot. La Sportiva strategically placed the synthetic overlays to provide excellent support and structure without adding weight to the shoe. An Ortholite Sockliner with anti-microbial and moisture wicking features adds to the wraparound feel and step-in comfort. The tongue is well-padded, fully gusseted, and stays in place all through the run. A TPU material that covers the eyelets to the midfoot help deliver a snug fit without being overbearing.
