The Scarpa Spark is an attractive and clearly well designed and manufactured trail running shoe. According to Scarpa North America, this shoe is a “Mountain Minimal running shoe designed for moving fast and confidently on rugged terrain.” Does the Spark fulfill this goal? Read on to see my verdict.
I received the Spark in the ocean and lime color way (it’s also available in black and green apple). My first impression was that the shoe looks more expensive than its list price ($119). The Spark weighs 9.2 ounces and has a 6mm heel drop. The shoe has an EVA midsole of impressive size, which promises a good measure of protection for sore feet.
The Spark has a gusseted tongue and a lacing system that securely holds the feet in place. The shoe fits comfortably a half-size up from walking shoe size. The Spark is narrow in the back and in the mid-foot, while providing plenty of room up front for one’s toes. The heel counter is low and there’s plenty of cushioning around the ankles.
The Spark’s insole fits well and did not present any issues. The laces stay tied.
I could feel the Spark’s great cushioning the second that I stepped out of my front door. The first trail that I encountered was a crushed gravel one, and the toothy, rugged Speed Lite outsole provided good traction on this surface. (The Spark’s feel on the trail reminded me of a pair of Nike trail running shoes that I once owned, the Nike Air Terra Kimbia.)
As I moved on to an asphalt road, I found that this model provides a stable ride. Neutral runners and minimal-to-moderate pronators should be able to use it as a road trainer.
The Spark’s strengths make themselves known on two surfaces. On hard-packed dirt trails it’s as if a stability control system was turned to “on,” keeping all the yaws in check. On hard rock trails, the toothy sole grabs and controls the rocks and keeps them from moving you sideways.
On sidewalks, the Spark is likely best for mid-foot strikers. There’s not much forefoot flexibility, and the shoe is not built for natural heel striking. The relative lack of energy return and bounce on concrete results in one’s feet staying close to the surface (as with the Asics GEL-Neo33 2), but this means that for some it will make a good mid-distance training shoe.
On a crushed gravel track, the shoe felt protective with one exception. My sensitive metatarsals sometimes complained when I was running laps in the Spark. It may be that this model could use some additional metatarsal area padding.
The Spark proved to be a very good fire road runner. The outsole lugs provide just enough surface grip to make a runner’s feet feel safe and secure. I would have no hesitation about wearing this shoe on wet weather days.
The Scarpa Spark is a highly protective shoe, considering its weight and price range. While the shoe does not feel “fast” in use, it nevertheless never feels like a boot. The outsole looks like it will hold up for hundreds of miles of wear and tear. All in all, it’s a pretty impressive package.
Verdict: The Spark is a trail running shoe that allows one to move confidently on mild, moderate and rugged, challenging terrain. It also performs well off the trail. While’s it’s best suited for mid-foot runners, runners of every ilk should be able to use the Spark as a safe, well-constructed and highly durable trainer.
