Not everyone wants a carbon plate for HYROX — and the data suggests they might be right. Carbon plates excel at forward propulsion during running, but HYROX demands far more than running. The functional fitness stations reward stability, ground feel, and versatility — qualities where non-carbon shoes often outperform their plated counterparts.
The Saucony Endorphin Speed 5 and the Brooks Hyperion 2 represent two of the best non-carbon options for HYROX. Both deliver impressive running performance without the instability concerns that come with aggressive carbon plates. But they take different approaches — and those differences matter on race day.

The Shoes
Spec Comparison
| Spec | Endorphin Speed 5 | Brooks Hyperion 2 |
|---|---|---|
| Weight (Men's) | 241g | 232g |
| Drop | 10mm | 8mm |
| Stack Height | 37/27mm | 38/30mm |

| Midsole | PWRRUN PB | DNA Flash v2 |
| Price | $170 | $160 |
Running Performance
Both shoes deliver race-worthy performance without carbon plate stiffness. The ride characters are different, however.
The Speed 5 uses PWRRUN PB foam — one of the best midsole compounds in running — combined with a nylon plate and SPEEDROLL rocker geometry. The result is a smooth, propulsive ride that makes transitions feel automatic. Energy return measurements of 78% in the forefoot put it in near-super-shoe territory.
The Hyperion 2 uses nitrogen-injected DNA Flash v2 foam and a SpeedVault plate that provides propulsive geometry without the aggressive snap of traditional plates. The ride is responsive but controlled — you feel fast without feeling unstable.
At 232g, the Hyperion 2 is 9g lighter than the Speed 5 at 241g. Across eight 1km segments, this is a marginal advantage.
Foam comparison: PWRRUN PB is bouncier and more responsive at speed. DNA Flash v2 is firmer and more consistent across all paces. Both are excellent — the choice comes down to whether you prefer a bouncier or more controlled ride.
Winner: Speed 5 — slightly better energy return and a more propulsive ride, though the Hyperion 2 is close.
Grip and Traction
Both shoes outperform carbon super shoes in this critical HYROX category. Their full-coverage rubber outsoles are designed for durability and multi-surface traction — qualities that translate directly to sled push performance.
The Speed 5's outsole provides reliable traction on indoor surfaces. Athletes report consistent grip during sled pushes and pulls.
The Hyperion 2's outsole uses a slightly softer rubber compound that provides excellent grip on hard, smooth surfaces — exactly what HYROX racing demands. The broader base also distributes force more evenly during sled pushes.
Winner: Tie — both provide solid grip for HYROX, significantly better than carbon super shoes.
Stability for Stations: The Hyperion's Strength
This is the Hyperion 2's defining advantage for HYROX. Brooks designed this shoe around stability, and it shows in every station.
The DNA Flash v2 foam is firmer than PWRRUN PB, which means less compression during lateral movements, single-leg lunges, and burpee broad jumps. The wider base and lower ride height create a planted, confident feel that is unmatched in this category.
Athletes who struggle with ankle wobble during sandbag lunges, who feel unsteady during wall balls, or who want maximum confidence on every station will notice the Hyperion 2's stability advantage immediately.
The Speed 5 is stable for a plated running shoe — but it is still a running shoe first. The bouncier PWRRUN PB foam and more aggressive rocker create slightly more movement during station work than the Hyperion 2.
Winner: Brooks Hyperion 2 — the most stable fast shoe available for HYROX.
Cushioning and Late-Race Protection
The Speed 5's PWRRUN PB foam provides a noticeably softer, more cushioned ride than the Hyperion 2's firmer DNA Flash v2. Over the full HYROX race — particularly during runs 6-8 when fatigue accumulates — the Speed 5 is more forgiving underfoot.
The Hyperion 2's firmer foam provides adequate cushioning for HYROX distances (8 km total running, broken into segments), but athletes who prioritize plush comfort will prefer the Speed 5.
Our analysis of 700,000+ results shows that runs 5-8 are where most athletes lose the most time. A more cushioned shoe can help preserve running performance in those critical later segments.
Winner: Endorphin Speed 5 — noticeably more cushioned and protective for late-race running.
Body weight matters here: Athletes over 80kg will generally appreciate the Speed 5's softer cushioning more than lighter athletes. If you weigh under 70kg, the Hyperion 2's firmer foam may actually feel better — more responsive and less mushy.
Durability and Value
Both shoes offer excellent durability compared to carbon super shoes.
| Factor | Endorphin Speed 5 | Brooks Hyperion 2 |
|---|---|---|
| Price | $170 | $160 |
| Expected lifespan | 500+ km | 500+ km |
| Training viable? | Yes | Yes |
| Race viable? | Yes | Yes |
Both shoes can handle daily training and race day. The Hyperion 2 is $10 cheaper, making it a marginally better value.
Winner: Tie — both offer excellent value and durability.
Who Should Choose What?
Choose the Endorphin Speed 5 if:
- You want the bouncier, more propulsive ride
- Cushioning for late-race protection is a priority
- You weigh over 75kg and need more foam underfoot
- You prefer a shoe that feels fast and responsive
- Running performance is slightly more important than station stability
Choose the Brooks Hyperion 2 if:
- Station stability and confidence are your top priorities
- You have struggled with ankle wobble or instability during HYROX stations
- You prefer a firmer, more controlled ride
- You weigh under 75kg and want a responsive feel
- You have wider feet (the Hyperion's toe box is roomier)
The Verdict
Key Takeaway
This is one of the closest comparisons in HYROX shoe selection. Both shoes are excellent choices, and the decision comes down to your priorities. The Endorphin Speed 5 is the better running shoe — bouncier, more cushioned, and more propulsive. The Brooks Hyperion 2 is the better station shoe — more stable, more planted, and more confidence-inspiring during lunges, wall balls, and sled work. For most HYROX athletes, we give a slight edge to the Speed 5 because running comprises the majority of your race time. But if station stability is your biggest concern, the Hyperion 2 is the smarter choice. Either way, you cannot go wrong at these price points.
