Review: La Sportiva Mutant: Very Supportive Upper, Great Cushion, Deep Lugs, and an Agile Forefoot. All for Less than 11 oz.

The La Sportiva Mutant is a highly supportive, deeply lugged trail shoe for rough mountain terrain: loose rock, snow, mud, etc.. Yet it is also perfectly fine on smoother terrain and has been more than decent for shorter road stretches due to its soft yet stabilized cushioning. It manages to pack a ski boot bootie type mid foot wrap tongue, debris proof sturdy upper, deep 6mm lugs, and road comfortable and not overly firm cushioning into a package weighing less than 11oz -10.9 oz 309 grams size Men's 9 EU 42, Women's 9.6 oz. To accomplish all of this must not have been easy! The shoe is aptly named as it really is a "mutant" combining features of ski boots and lightweight running shoe design in neat new ways.

The Upper is the Star
The upper is one the most evolved and carefully considered for purpose, rough terrain, I have seen in a trail runner or for that matter any running shoe. The Mutant features two innovative upper technologies which to date work as intended.

Guest Review: LaSportiva Helios SR- A Strikingly Light, All Terrain Capable, Very Refined Trail Runner with One Flaw.


Editor’s Note: I am tickled to offer this review of the Helios SR authored by Dominick Layfield. Dominick is one of the speediest trail and ultra distance runners in Salt Lake City and Park City, Utah. Often on the podium, and with many long trail races under his belt, he prefers agile light trail runners such as Nike Terra Kiger and Montrail Rogue Fly.
Dominick won the 2015 New Year's Day 5 Hour Run at the Utah Olympic Oval, running 39 miles!

First Impressions:
Putting the shoes on indoors, my first impression was how elasticated and snug the shoe feels.  Due to the sock-like fully-gusseted shoe liner/tongue construction, the laces felt almost superfluous. I could run in the shoe with the laces untied.

Yesterday, I ran 16 miles on smoother trails at Antelope Island, UT in the Montrail FluidFlex ST, 9.2 oz/266 grams, a good value at $95 including from Running Warehouse here .  Really enjoyed the stable ride due to the  Fluid Foam which mixes different densities of the same material into a single midsole layer the Fluid Frame, the firm but decent cushioning, and a very supportive upper with decent toe room.  A shoe with mild pronation support,and I usually cannot stand support or stability shoes, I did not notice the firmer mid sole mid foot and welcomed a bit of extra support there on the trail. Very flexible at one deep groove towards the mid foot. Front of that, towards the toes, less flexible, stiffer due to firmer EVA in the mold serving as a rock plate, a bit awkward feeling on moderate climbs but felt great on steeper climbs, downhills, and flats.

Did some shoe testing/comparing this morning on the indoor track. 40 easy minutes, 20 in the adidas adizero XT Boost, coming 8/1 and then 20 minutes in the LaSportiva Mutant. I like to get a feel for shoes on a consistent surface before taking them out on the roads and trails. Update: since I have raced in the adizero XT Boost and done 2 trail runs in the Mutant.
