The Scarpa Spin is a very light shoe that combines aggressive lugs for optimal traction with a sensitive ride. With a low 4mm heel-toe drop it is stable and precise and is ideally suited to steep and technical terrain. As a light, sensitive shoe it understandably does not offer the same level of underfoot protection that maximally cushioned shoes do, so it better suits faster, shorter distance running efforts, and makes for a great racing shoe. If speed in the alpine environment is what you are looking for, the Spin is one of the first shoes you should check out.

Our Analysis and Test Results
The Spin is the second lightest shoe in this review, but also comes with a few exciting features. We enjoyed having the lace garage on the top of the tongue for tucking away our laces, so they don't easily come un-tied. Likewise, we appreciate the fact that this shoe comes with two different insoles that can be swapped out as desired. One insole is very thin and lacks much cushioning, while the other pair offers more arch support and also takes up more volume. Swapping the insoles out gives the shoe a slightly different feel overall allowing you to tailor the amount of cushioning as well as the fit to your personal preferences. This is a feature that we wish all running shoes came with!
Underfoot, the Spin uses two layers of different density EVA foam as cushioning and protection from rocks. However, large cut out areas in the outsole and through the midsole foam mean that the landing surface is not uniform, and depending on what part of your foot lands on a sharp object like a rock, you may feel nothing at all or feel like you are being stabbed right in the arch of the foot. We often find that underfoot protection and sensitivity are polar opposites when it comes to assessing the feeling of a shoe, and in the case of the Spin, sensitivity seems to be greatly favored over underfoot protection. The upper is made of breathable mesh with thin welded overlays that do an effective job of covering all the areas of highest wear.
Unfortunately, the toe bumper is only lightly padded and doesn't offer a significant amount of protection from accidentally kicking a rock. Overall this shoe is not the most protective but intentionally emphasizes other things. We awarded 5 out of 10 points.
The outsole of this shoe is made with Vibram rubber, and features offset arrow shaped lugs that are roughly 4 mm deep. It also has many gaps where the rubber and midsole are cut out, revealing the exposed high-density foam insert underneath. Despite the seemingly aggressive lugs, we found that this shoe did not grip as well on steep loose dirt, or on dry rock, as we would have expected. We surmise this is because the lugs are not cut square to the ground, but are rather rounded off on some sides, angling gently back to where they join with the outsole so that there isn't as much of a sharp edge that can dig into softer terrain. It grips roughly as well as the New Balance Fresh Foam Gobi Trail v2.
Despite the narrow landing platform, this shoe is exceedingly stable across all types of terrain. In our dedicated side-hilling testing, we noticed that this shoe feels low to the ground with little difference in the heights of the heel and toes (4mm). The shoe does an excellent job of gripping and holding the foot securely in place with an interior sock-like fit.
We noticed very little to no propensity for this shoe to roll to the side, and no discomfort around the ankle bones from the shoe catching our feet on steep side-hills. Our feet pretty much never slipped forward, either. We rated this shoe near the top of the pile, giving it 9 points for this metric, the same as our Editors' Choice award-winning Nike Air Zoom Terra Kiger 4.
This is a very comfortable shoe, although folks with wide feet may be discouraged to hear that the fit is particularly narrow throughout, especially in the forefoot and the arch. The sock-like interior sleeve does a great job holding the foot firmly in place with no discomfort, and we love the choice of footbed inserts that allows one to choose whichever one leads to a more comfortable fit.
We enjoyed wearing the Spin with the thicker insole in place better as it gave us more cushioning underfoot and slightly more arch support as well. In the water bucket test, we discovered that the Spin was slightly above average when it came to absorbing water, meaning that it absorbed less water weight than most. However, it was one of the poorer choices at drying out quickly. All told we think this is a comfortable, if quite snug and narrow, shoe.
Weighing in at a mere 19 ounces for a pair of men's size 11, these were the second lightest shoes we tested, behind only the Hoka Evo Jawz. Lightness is one of the main reasons that people will be interested in purchasing this shoe, making it a particularly fitting selection for uphill oriented running where every ounce counts.
As we mentioned when discussing the underfoot protection, this shoe has a pretty decent amount of dual density EVA foam in some places. In others, the lighter, thicker foam has been cut out, leaving large voids in the outsole where the pointy end of a rock can really cut through the protection. Overall this shoe is far more sensitive than it is protective, and it is also extremely flexible.
Held in the hands, one can very easily bend it and twist it from side to side. Prospective purchasers should be desirous of a nimble, flexible, and very sensitive ride or they will likely feel disappointed. Comparing it to others that we tested, it is most similar to the thin and flexible Topo Athletic Runventure 2.
The Spin strikes us as a borderline specialty shoe with short, steep, and technical terrain serving as its bread and butter. Think SkyRunning, vertical kilometer races, or a race shoe up to half marathon distance. Of course, this isn't to say that some people won't enjoy running in it as an everyday shoe, but it likely won't live up to that level of abuse for long. If you want the perfect shoe for your best effort at the Pike's Peak Ascent, this is the one.
Retail price for this shoe is $130, making it one of the more expensive ones on the shelf. While we think this is an excellent shoe for the right person and purpose, we think that the majority of runners will find better value from an everyday, rugged trail shoe that has a wider range of use and can handle more miles.
The Scarpa Spin is a very light and form-fitting shoe that is ideal for running your fastest on race day, especially if the hills are steep. It is quite comfortable and gives one the choice of two different footbed insoles to customize the fit, but in general is on the narrower side of the spectrum. It makes for a great, high performing addition to any runner's quiver, but wouldn't be our top recommendation for a one-shoe-does-it-all shopper.
