What we like about the Arc’teryx Vertex Speed Low
MICHAEL: Typically, when I review a shoe, I might start by discussing its upper, work my way down through the midsole, and finish with the outsole or vice versa. However, the unique climbing shoe-inspired look and construction of the Vertex Speed Low invite me to approach (no pun intended) this shoe from heel to toe.
Starting at the heel, you’ll find that the Vertex Speed Low feels and behaves like a normal, modern running shoe, featuring a sleek, minimally padded heel counter with a cushioned and responsive midsole directly underneath. Like any other shoe, the midsole is soft and exposed, allowing it to compress and rebound on steep descents. Above the midsole, a thin, yet surprisingly secure heel collar provides security, and despite the lack of cushioning evident to the naked eye, I found the achilles area to be quite comfortable and undoubtedly secure. An angled chevron lug pattern below provides braking and control on steep descents.
Moving onward toward the toe box of the shoe, we encounter the lacing chain, which is substantially longer and features more eyelets than most other trail running shoes. No doubt, this is likely influenced by climbing and approach shoe design, and I really, really enjoyed it in the Vertex Speed Low. For a shoe that exudes precision (both in its niche application as well as its own fit), this was a welcome feature. I firmly believe that a secure, next-to-skin fit is paramount for technical trail running, and the Vertex Speed has it in abundance.
Beneath this lacing chain towards the shoe’s forefoot, we come across a change in midsole appearance and function. Instead of the exposed, cushioned heel, Arc’teryx wrapped this portion of the outsole in Vibram Litebase compound, which extends up from the outsole to form a formidable layer of protection around the toe. Such a design is undoubtedly inspired by the looks of approach shoes, and I dig it. In addition to the visual changes, the midsole foam exhibits a noticeable difference in density. Instead of keeping things soft like the heel and midfoot (potentially introducing instability or imprecision in the forefoot), Arc’teryx firmed up the compound to instill even more confidence in every step.
