Arc'teryx Vertex
The Arc'teryx Vertex is a hybrid approach-trail running shoe line featuring the Vertex Alpine (336g) and Vertex Speed (230g) models. The Alpine features a Matryx woven polyester upper, a Vibram XS Flash 2 outsole with 4mm lugs, an EVA/Polyolefin midsole with a TPU shank, and an 8mm drop (18mm heel, 10mm toe). Available in standard ($200) and GTX waterproof ($250) versions. The Speed features a lighter construction, a dual-density midsole, and a built-in stretch gaiter for $180. Colors include Black, Black Sapphire, Tatsu & Edziza, Solitude & Graphite, Euphoria & Graphite, and Canvas/Graphite. Sizing runs narrow, with a precision fit requiring a break-in period. Best for technical trails, alpine approaches, and scrambling up to 5.10- climbing. The narrow last accommodates average to narrow feet better than wide feet. Designed in Arc'teryx's Portland footwear office as the first in-house shoe design.
How Does Arc'teryx Vertex Sizing Run?
The Vertex sizing runs small and narrow. Most reviewers recommend sizing down half to full size from your normal running shoe size, though some find true-to-size works perfectly. Arc'teryx calls this a "precision fit," which creates a snug feel across the forefoot.
The narrow last requires breaking in for wider feet. If you plan to primarily climb and scramble, stick with your normal street shoe size. For equal running and climbing, size up by half a size. The integrated knit collar creates a sock-like fit that's initially difficult to pull on but seals out debris effectively. The precision fit works best for average to narrow feet.
Scrambling First, Running Second
The Vertex Alpine leans toward scrambling rather than being a true approach shoe. The design prioritizes trail running comfort while adding sticky Vibram XS Flash 2 rubber and a climbing zone at the toe. The shoe handles terrain up to 5.10- climbing, but can't replace dedicated rock shoes.
For pure approach performance, the La Sportiva TX4 provides better climbing capability. However, the Vertex excels at fast alpine ascents that require approach running and technical scrambling without shoe changes. The Vertex Speed shifts further toward a 230g weight, with a dual-density midsole that places firmer foam in the forefoot for scrambling precision.
Matryx Upper Survives 100+ Miles on Granite
The Matryx woven polyester upper proves surprisingly durable despite its lightweight appearance. Reviewers reported over 100 miles with zero premature wear, no holes, and intact rand adhesion. The material handles granite abuse while maintaining breathability.
The Matryx resists abrasion better than typical trail runner mesh. The material brushes off moisture in light conditions but wets out in persistent rain. The durability makes it practical where traditional trail runners would fail, and the fabric holds up to jamming cracks without tearing.
Built for Steep, Rocky Terrain
The Vertex excels on technical trails with rocky, uneven terrain. The Vibram XS Flash 2 rubber provides excellent grip on rock slabs, and the 4mm lugs deliver traction on loose surfaces. The TPU shank creates stiffness for edging while maintaining flexibility.
The shoe performs best on steep, technical terrain where precision matters. It feels clunky on flat trails but shines on rocky climbs and descents. The integrated collar prevents debris during scree descents, and the TPU toe cap handles sharp granite. For mellow trails, lighter options like the Arc'teryx Norvan LD 4 provide better comfort.
Plan for 5 to 10 Shorter Outings First
The Vertex requires significant break-in time, comparable to that of climbing shoes. The narrow last and stiff construction need multiple shorter runs before comfortable all-day wear. Reviewers suggest breaking them in on shorter approaches before committing to longer routes.
The integrated sock construction contributes to break-in difficulty. Plan for 5-10 shorter outings before trusting the Vertex on long missions. Users who skip the break-in report blisters and discomfort.
336g Alpine vs. 230g Speed
The Vertex Alpine weighs 336 grams per shoe, making it heavy for a trail runner but light for an approach shoe. Testers felt the extra weight on the longest runs. The Vertex Speed addresses weight concerns at 230 grams (low version) or 240 grams (mid version with gaiter), making it packable for multi-pitch routes.
Premium Pricing for a Niche Hybrid
For climbers needing one shoe for technical approaches and moderate scrambling, the Vertex Alpine delivers strong performance. The $200 price ($250 for GTX) positions it as premium gear, though durability and hybrid capability justify the cost. The Matryx construction lasts longer than standard trail runners.
The narrow fit limits the audience to average and narrow-footed users. The break-in requirement makes this unsuitable for casual users wanting immediate comfort. For fast-and-light alpine missions, the Vertex Speed at $180 provides better value. Check Arc'teryx's website for current availability.
