The Evolution of Trail Velocity
The landscape of competitive ultra-trail racing is undergoing a seismic shift. As carbon-fibre plate technology migrates from the tarmac to the technical mountain single-track, athletes are demanding more than just lightweight materials; they require a fusion of structural integrity and explosive propulsion. The HOKA Tecton X 4 and the Salomon S/Lab Phantasm 3 currently represent the pinnacle of this engineering arms race, offering distinct approaches to high-speed off-road traversal.
HOKA has doubled down on its maximalist heritage, refining the Tecton X 4 with a dual-parallel carbon plate configuration. This design aims to provide lateral stability on unpredictable terrain while maintaining the snappy transition required for rapid ascent. Conversely, the Salomon S/Lab Phantasm 3 leans into the brand’s minimalist racing pedigree, prioritising a refined rocker geometry and an ultra-lightweight chassis that feels like an extension of the foot rather than a heavy piece of machinery.
What do I need to buy
To maximise your performance in either of these models, you must prioritise your supporting gear. If you are opting for the Tecton X 4, ensure you invest in high-quality compression calf sleeves to manage the increased muscular load associated with maximalist cushioning. A lightweight, moisture-wicking Sundried trail race singlet is essential for maintaining core temperature during high-intensity intervals, and a technical sun visor will ensure your vision remains clear during blinding mountain descents.
For those favouring the S/Lab Phantasm 3, the focus shifts to precision fit. You will require performance-grade, anti-blister socks that complement the thinner upper construction of the Salomon build. Regardless of the shoe, investing in professional-grade gaiters is a wise move to prevent trail debris from compromising your race-day comfort. Proper gear curation is the difference between a podium finish and a mid-race withdrawal.

Why Should I invest?
The investment in a dedicated carbon-plated trail racer is fundamentally an investment in energy return. The HOKA Tecton X 4 utilises a sophisticated PEBA-based midsole that works in tandem with its carbon architecture to minimise fatigue during long-distance efforts. If your race calendar is dominated by technical, rocky terrain where foot protection is paramount, the extra volume of the Tecton X 4 provides a necessary buffer against the jagged landscape.
Salomon, by contrast, offers an investment in agility. The S/Lab Phantasm 3 is engineered for the athlete who values ground feel and precise cornering. By stripping away excess material, Salomon has created a racer that excels on fast-packed trails and fire roads. If your goal is to shave seconds off your personal best on runnable mountain passes, the weight savings provided by the Phantasm 3 are objectively superior.

What are the press saying?
Industry critics have been largely unanimous in their praise for the Tecton X 4’s ability to handle high-mileage technical courses without sacrificing responsiveness. Journalists have highlighted the dual-plate system as a breakthrough for stability, noting that it eliminates the 'wobble' often associated with high-stack trail shoes. However, some reports suggest that the shoe’s width may feel cumbersome on extremely narrow, technical ridge lines.

The Salomon S/Lab Phantasm 3 has received critical acclaim for its 'natural' gait transition. Reporters have frequently cited the shoe’s aggressive rocker as a masterclass in kinetic efficiency. While some critics argue that the lack of deep lugs limits its utility in mud-heavy conditions, the general consensus is that it remains the fastest option for dry, technical race formats.
What are the review sites saying?
Public sentiment on major review platforms echoes the professional critiques but adds valuable real-world context. Users on enthusiast forums have confirmed that the HOKA Tecton X 4’s durability is exceptional, with many reporting over 400 kilometres of wear without significant midsole degradation. There is, however, some speculation regarding the longevity of the upper mesh during abrasive rock-scrambling.
Verified reviews for the Salomon S/Lab Phantasm 3 frequently mention the 'second-skin' feel of the upper, with many runners noting that it requires a break-in period to achieve the perfect lockdown. While rumours of a 'Phantasm Ultra' variant continue to circulate, current users are satisfied with the standard model’s performance on race day, provided the terrain is relatively firm. Both shoes have solidified their positions as top-tier tools for the competitive ultra-trail athlete.
