Saucony Endorphin Speed 4 vs Hoka Mach X: Which Plated Trainer Deserves Your Money?

Introduction

Plated super trainers promise a bit of everything: comfortable enough for daily training, lively enough for tempo work, and in some cases even race-day ready. Two of the most talked-about options right now are the Saucony Endorphin Speed 4 and the Hoka Mach X. On paper they look similar, but after spending real miles in both, the differences in ride, fit and versatility become clear. Here is how they stack up.

At a Glance: Specs and Pricing

The Saucony Endorphin Speed 4 costs £180 or $170, weighs 239g (8.4oz) for men in a size 8, and has an 8mm heel-to-toe drop. The Hoka Mach X weighs 242g (8.5oz) for men in a size 8 with a 5mm drop. Both sit firmly in the super trainer category, built for daily training with a plate in the midsole to add propulsion at faster paces.

Saucony Endorphin Speed 4: A Refined All-Rounder

The Endorphin Speed 4 takes learnings from its popular predecessors and refines rather than reinvents. The most important change is a re-engineered wing nylon plate that provides additional reinforcement while maintaining flexibility. There is also an updated mesh upper designed to give a more secure fit than the slightly roomy Endorphin Speed 3, and a new waffle Pwrtrac outsole rubber that improves grip and durability noticeably, especially on wet surfaces.

Underfoot, the shoe still uses Saucony’s PWRRUN PB foam combined with the brand’s Speedroll technology, delivering strong propulsion when you pick up the pace while keeping the ride smooth. The platform feels slightly softer and more cushioned than the Mach X, a touch wider, and more protective. Even at easier paces it stays comfortable without forcing you to run fast.

That is the real story here: the Speed 4 is one of the most versatile super trainers we have run in. You can use it for easy runs, daily runs, long tempo efforts and even marathon pace intervals. Plenty of runners buy it as their one and only shoe, train for a marathon in it, and race it. It earns its higher price simply because it can do so much.

Hoka Mach X: A Cruising Shoe With a Rocket Rocker

The Hoka Mach X was built to take the learnings from the impressively versatile Mach range and add a propulsive carbon plate. That plate sits between two layers of EVA foam to provide a supportive ride, with a PEBA section on top to improve responsiveness and rebound. The idea is a shoe that feels soft for easy sessions but has pop for faster efforts. Other features include a creel jacquard upper for breathability, a gusseted tongue and a generous layer of outsole rubber.

In practice, the Mach X delivers a distinctive ride. There is an immediacy and high-turnover clip to it, with that classic Hoka rocker rolling you through each stride from heel strike. The foam does not sink much and comes back quickly, which gives it a lively, energetic feel. The trade-off is a firmer, more direct platform that offers less cushion protection over long, slower efforts.

Where it shines is steady, consistent cruising. During marathon training, at a challenging but controlled pace, it feels efficient and fluid. It is less convincing at both extremes: not the most engaging option for genuinely easy runs, and not explosive enough at the sharp end compared with the Speed 4. It does not gain a huge amount from the plate, so it ends up feeling more like a niche cruiser than a true super trainer.

Fit and Sizing: Narrow Versus Roomy

Both shoes ran true to size in testing, with good midfoot lockdown and secure heels. The meaningful difference is width. The Hoka Mach X comes up snug, particularly around the big toe knuckle and into the toe box. If you have wide feet or like a roomier fit, going half a size up is worth considering.

The Endorphin Speed 4 offers a slightly wider, more accommodating fit than the Mach X, and unlike the Speed 3, which some found too roomy, the updated upper here held securely with no heel slippage. Overall, the roomier fit belongs to the Speed 4, while the Mach X has a more dialled-in race-style fit.

Ride Feel: Cushion and Protection Versus Direct Pop

Side by side, the personality gap is obvious. The Speed 4 lands flatter with a little more cushion, then the plate kicks in and delivers a noticeable bounce. It rolls through foot strike smoothly with the Speedroll rocker, and despite its high stack it retains a grounded, nimble feel. It feels lighter and more aggressive than the numbers suggest, with a faster transition onto the forefoot.

The Mach X feels more direct and immediate, with the rocker creating almost a bowl of foam underfoot that engages quickly as it rolls you forward. It is well suited to speed-focused workouts, but over longer distances it feels a touch bigger and less lively, slightly ponderous when you really push the pace. If you value a big, responsive, rocket-like ride with a lower drop, the Mach X delivers that feeling. If you want cushion, protection and still decent speed, the Speed 4 is the safer platform.

Outsole and Grip

The new waffle Pwrtrac outsole on the Endorphin Speed 4 is a genuine highlight, offering solid grip on wet surfaces with no issues in testing. The Mach X outsole is okay but noticeably smoother and less grippy. No slipping occurred in it, but the Speed 4 clearly has the edge here.

Verdict and Buying Advice

If you are buying one shoe to do everything, the Saucony Endorphin Speed 4 is the pick. It is the more versatile, more impressive super trainer, comfortable at easy paces yet genuinely quick for tempo runs, marathon pace work and even racing. The extra money is justified because it replaces the need for several other shoes in your rotation.

The Hoka Mach X is a pleasant, comfortable cruiser that suits relaxed daily runs and steady marathon-training sessions, and it could even be the livelier choice for a half marathon race. But it lacks the top-end energy and versatility you want when paying for super trainer technology. If you love an aggressive rocker and a snug race fit, it can work, especially half a size up. Alternatives worth considering include the New Balance Rebel v4, a versatile unplated option, and the regular Hoka Mach series (the Mach 4 and 5), which some runners prefer to the Mach X for training versatility.

Conclusion

Both are impressive, capable fast daily trainers, and the call is closer than expected. But the Speed 4 simply has more in its locker: a wider range of paces, a roomier fit, better grip and long-run protection. For most runners looking for one plated trainer to do it all, the Saucony Endorphin Speed 4 edges it.
