    A high-speed rally car for your feet: Hoka One One Speed Instinct 2 review

    The Speed Instinct 2 is just about perfect for trail runners who don’t want to sacrifice all-terrain grip or ample cushioning but still need a lightweight shoe for moving fast.

     

    Who the Speed Instinct is perfect for

    Hoka deserves a pat on the back for designing this shoe. The maximalist category of pillows-on-your-feet running shoes to which Hoka belongs is often criticized for being amply cushioned, but also chunky, awkward, and heavy.

    For races shorter than an ultra-marathon, or for more up-tempo training runs, you just don’t want mattresses tied to your feet.

    Hoka seems to have acknowledged these limitations in its maximalist line by offering runners the Speed Instinct, which doesn’t sacrifice cushioning, but also is nice and light (9.5oz for a men’s size 9) and is packed with design features that help you zip along quickly on the trails.

     

     

    Starting from the ground up, the Speed Instinct’s outsole is terrific: it looks like it was modeled after a monster truck tire and delivers perfect traction over a wide range of conditions. I’ve run comfortably on dirt, mud, snow, ice, grass, sand, boardwalks, and pavement in this shoe, and the outsole has kept its grip for well over 300 miles.

    The outsole also succeeds in its moderation: it has fairly moderate lugs that don’t make the mistake of many trail shoes that are way too aggressive, packed with great white shark’s teeth grommets that make the shoe uncomfortable on anything but sloppy mud and add unnecessary weight (e.g. the Salomon Speedcross).

     

     

    Moving up on the shoe, the midsole is terrific. It has the shock-dampening, soft, cushiony feel we’ve come to expect from Hoka, and keeps your legs feeling fresh up to about a marathon distance trail run.

    At the same time, compared to your average Hoka (say, the Stinson ATR 4 or the Speedgoat), it is a little more responsive, has a more traditional stack height, and has a nicely curved shape that rocks you smoothly through the gait cycle towards an easy toe-off.

    All of these features lead to a fast-feeling shoe that makes it easy to run at a quick tempo. I’ve also found the midsole maintains its structure, cushioning, and energy return for well over 300 miles.

    Upper & fit

    Finally at the top of the shoe, the upper of the Speed Instinct 2 is very well designed. It is mostly seamless, giving a smooth, sock-like fit that breathes and drains moisture quickly, whether from sweat or stepping through puddles.

    It is built on a last that will accommodate a wide range of foot types, keeping snug in the heel and midfoot while giving plenty of space in the forefoot for wider feet, and foot swelling that occurs on long runs.

    The upper also has some thin overlay designs along the midfoot that provide a comfortable snugness and keeps the foot saddled even on technical terrain.

    The upper also has a rigid heel shank, unlike the Speedgoat, that adds stability and reduces slip. Finally, it’s a minor touch, but the stretchy laces on the Speed Instinct 2 are a nice touch – they’re durable and also stay locked down even when wet. Thanks to this well designed upper, I felt very confident with foot placement even in rocky conditions with rapid elevation change.

    My one complaint with the upper was that it kept its form well up to around 300 miles, however, at this point (like many seamless upper constructions) it began to stretch out and lose its snugness around the forefoot and midfoot, presenting real issues on technical terrain where the foot needs to remain locked in place, or risk slipping or rolling an ankle.

    The upper was the first part of the shoe to break down, and if it was more durable, the midsole and outsole could easily have handled more miles. That said, for a lightweight shoe, the upper’s durability was perfectly acceptable, and a marked improvement from the Speed Instinct 1.

    A Look at the competition

    There aren’t a whole lot of shoes in direct competition with the Speed Instinct 2: most either aim to be much lighter obstacle course running shoes or are significantly heavier traditional trail shoes and ultra-running shoes. The speedy, high cushioned niche is a small patch of terrain.

     

     

    Two competitors may be the Brooks Mazama and the Salomon Sense Pro 2. Both are trail shoes with similar versatile outsoles to the Speed Instinct and a similar goal of being lightweight and race-ready at 9.3 and 9.2 oz respectively for a men’s size 9.

    However, both of these competitors are extremely firm, even hard, to a degree that I found very uncomfortable on any run over about six miles, even on the soft, muddy ground. By contrast, the cushioning in the Speed Instinct keeps feet feeling happy up to about a marathon distance, even on hard rocky terrain.

    Another competitor is the Altra Superior 3.5. However, the Superior is heavier at 9.6 oz, has a less grippy outsole that slips on rocks and leaves, an awkward heel-toe transition because of its flat, slab-like midsole, worse durability, and a very wide toe-box last that won’t fit well for as many foot shapes.

    All in all, I found the Speed Instinct was superior in every way (pun intended).

     

    Who the Speed Instinct isn’t ideal for

    Although it is just about perfect for trail runners looking for a shoe that can handle both fast runs and high mileage, the Speed Instinct isn’t ideal for everyone. Runners who might look elsewhere are:

    1. Overpronators, runners who need some arch support. The Speed Instinct 2 is completely neutral. That said, stability trail shoes are virtually non-existent, and the Speed Instinct has a removable sock liner, deep footbed, and a heel shank that makes it very effective at accommodating supportive inserts.

    2. Ultra-runners looking to go beyond the marathon distance should probably look at more built up shoes in Hoka’s line like the Speedgoat or Stinson ATR, or other maximalist trail options like the Altra Olympus. I found that after about 20 miles, higher stack height and softer midsole of the Stinson ATR was worth the extra weight when compared to the Speed Instinct.

    3. Road runners or even those running on smooth crushed gravel trails will find the Speed Instinct’s trail-tuned outsole unnecessary and heavy. There are lighter weight road shoes that will do just fine.

  • 87 / 100 | Believe in the Run

    With the absence of a rock plate, I believe the Speed Instinct 2 is undoubtedly a winner for smoother trails.

  • 86 / 100 | Ultrarunner Podcast

    It’s a great everyday trail runner that serves double-duty as a trail race shoe up to 50 miles in most situations.

  • 88 / 100 | Profeet

    What really caught my attention though was the promise of a new wider toe box – hurrah!

Updates to Hoka One One Speed Instinct 2

  • Most of the components and features that graced the original Speed Instinct is still present in the Hoka One One Speed Instinct 2. The platform still houses a specific cushioning system that’s prevalent in many of the brand’s stable of running shoes. The outsole also retails the trail-ready gripping lugs that aren’t too aggressive.
  • However, the upper unit now has an updated design. A seamless construction is still in place here, but the overlay system has been reinvigorated to accommodate a snugger and more agreeable fit. Thin yet strong overlays have been fused directly to the upper’s fabrics, providing structure to the material. But they’re strategically placed to give the foot more security, especially when the shoelaces are adjusted.

Hoka One One Speed Instinct 2 size and fit

The Hoka One One Speed Instinct 2 has a standard running shoe length. It follows the regular preferences of runners when it comes to sizing. The available width for both the men and women’s versions is medium. The semi-curved shape of this running shoe adheres to the natural curve of the human foot.

Outsole

The outsole unit of the Hoka One One Speed Instinct 2 makes use of the High-Abrasion Lightweight Rubber. It’s a sturdy material that aims to shield the mid-sole from the abrasive nature of the trails. It also doles out traction, which is essential for the outdoor adventures.

Gripping lugs pockmark the surface of the outsole. They’re designed to heighten traction and hold over uneven surfaces. They’re not too aggressive in size, so runners won’t have a hard time transitioning from the trails to more even ground.

Midsole

A rocker design is employed in this running shoe’s platform. Called the Early Stage Meta-Rocker Design, it allows the foot to move through the gait cycle with ease and sureness.

The Pro2Lite +10 is a cushioning foam that’s designed to provide underfoot comfort and protection from impact. It has a soft heel section, thus making foot-strikes more agreeable. The forefoot is firmer, so it causes the toe-offs to be springy and enabled.

Upper

The upper unit of the Hoka One One Speed Instinct 2 features the Seamless Air Mesh. It’s soft, smooth and it doesn’t have a substantial weight. It accommodates the flow of air into the foot-chamber, therefore maintaining a cool and dry interior environment.

The 3D Puff Print Frame is made up of thin overlays that have been printed onto the main upper fabric. Its purpose is to reinforce the structure of the shoe, yet it also gives a snug and secure coverage for the runner’s foot.

A Reinforced Toe Cap is added to shield the forefoot from debris and aggressive surfaces on the trails.

Hoka One One placed a traditional lacing system to allow a customizable fit.

The pull-tab on the rear of the upper makes it easier for runners to wear and remove the shoe.
