Helios SR

Helios SR

$130.00
Boasting a dual-compound outsole that integrates sticky rubber on the forefoot and transitions to a more durable compound on the heel, the Helios SR is ideal for racing or training. This highly breathable, lightweight trail runner will keep you moving fast in variable conditions. Slightly more cushioned than the Helios 2.0, the Helios SR is our lowest-drop Mountain Running® shoe.

Favorite LaSpo shoe
The original helios are perfect for roads and buffed trails, and these are perfect for EVERYTHING. Took them on a maiden voyage up Longs and felt like I was in a pair of racing flats that still protect my feet. Obviously if you have a giant rock or stick jam up into the foam ridges, you can feel that impact, but it's always minimal and not a big deal compared to the comfort and speed of the shoe. I've yet to wear them for over 50k (30mi), but would wear them for something like Western States or Leadville. Maybe not UTMB or anything more rocky.

Great shoe for roads
I know this shoe is technically for trails, but I've been using them for roads and really like running on pavement with them. They are also very good for dirt roads, slick rock, and similar terrain. They are not very good for terrain with lots of small sharp rocks as the sole is pretty flexible and light. Shoes are very light and comfortable.

Almost perfect, ruined by sole
Great fit and feel but the foam voids in the sole are downright dangerous. Please just cover the whole sole with that nice sticky rubber. I’ve had two pairs but I think I’ll have to pass for now on after too many times being stabbed in the foot by sticks, rocks, cactus, etc.

Dissapointed.
First of all the shoe is x1.5 size smaller. No kidding.
There is a noticeable gap between the perceived quality of the La Sportiva clothing (which is superb) and shoes (which leave mixed impressions).

Loved this shoes, but my feet said enough!
Love this shoe, this is my 3rd pair so far, and it is super light, very low drop, and fits like a glove, but the main reason I will not buy it again is because of its sole. Rocks poke in, and the sole lasts very little. Expect no more that 3 months of running in rocky terrains and the soles will become unusable. Many other runners mentioned the need of a rock plate. I agree, and change the design of the sole, having a full outer sole.

Great Shoe But Really Needs a Rock Plate!
Great shoe! But can we please put a light weight fore-foot rock plate in the next version? I rather take an ounce of weight for protection after 80 miles things start poke through and it freakin hurts!

Other than that this is a outstanding trail runner. But a rock plate should be standard.

My new favorite trail running shoe
I am going on the second pair of Helios SR. This is my new favorite trail running shoe, now that the original Helios cannot be purchased anymore. Compared to Helios, Helios SR feels a bit softer and the fit a bit more snug, but nevertheless it is very comfortable. It handles some amount of roots and rocks just fine, but I wouldn't wear it for an overly rocky trail because sharp rocks can occasionally poke though the outsole. Compared to the original Helios I really like slightly stretchy shoelaces on the SR which stay tied and don't need much adjustment. The only negative that I can think of is that the outsole wears rather quickly. Overall this is a great shoe!

Awesome shoe if you like a 2-4mm drop, just watch the sharps on the soft spots!
Overall a really good shoe if you want a 2mm drop. Everyone else is right when they say these run slightly small. I usually wear a 44, and that size in this shoe was a bit tight in the toe for the first 20 miles or so. After that they felt great. The 2mm drop, the sticky rubber, and the tread make them super responsive and fun on technical terrain. I'm grateful for their light weight at the end of long runs.

The cons: the ridges in the sole that are covered by sticky rubber are great, but god forbid you step on a sharp edge in the soft spots in between. I have an unlucky spot on my big toe that meets an angry rock once at least once a run. The toe cap is also delaminating after about a month of use.

Highly recommended for any trail running and racing.
By far my favourite shoe. I've been running on mountainous terrain and trails for many years. This is a great natural lightweight running shoe with ample cushioning. Super grippy as well.

Great all terrain shoe
Ran the Leadville Heavy Half Marathon in this right out of the box. They worked excellent. Definitely a do it all shoe. I was tossed between the 46 and 46.5 as they both had snug heels but went with smaller size, just based it on what felt most natural to my foot. Feels very secure and hugs the foot nicely without strangling it.
