user: I want to run try running a marathon in under 3 hours. What shoe can you recommend me, so that I'd have the best chance of doing that?
assistant: A sub-3 marathon is a serious goal — that's roughly 6:52/mile pace — and the right shoe can absolutely help you get there. Before I lock in a recommendation, I need to understand your biomechanics and preferences a bit better, because the best race shoe for a sub-3 attempt depends on how you run.
**A couple quick questions:**
1. **What's your current footstrike?** Do you land on your forefoot, midfoot, or heel? (This matters a lot — some of these racers are optimized for forefoot strikers, others reward midfoot runners.)
2. **How much do you weigh, and what's your typical race-day cadence?** Lighter runners and higher-cadence runners get different benefits from these shoes — some reward speed and turnover, others prioritize cushioning and stability.
3. **Have you raced in a carbon-plate shoe before, or would this be your first?** Some shoes are more "forgiving" for first-time super-shoe users; others demand good form to shine.
Once I know those details, I can narrow down which of these elite racers will give you the best edge for a sub-3 push.
user: Lighter runner, 180-185 steps/min, can be higher when tired. Midfoot striker. I did race in Metaspeed Sky+ before (a couple models before the current Tokyo one), was okay-ish for the half-marathon, though even there it was tricky closer to the finish line, when my form degraded.
assistant:
Good intel — that experience with the Sky+ tells me a lot. You're a lighter, higher-cadence midfoot striker, and you found the Sky+ a bit twitchy when fatigue set in. That's the classic ASICS Metaspeed problem: brilliant pop and responsiveness when you're fresh, but the soft foam and minimal stability can feel unpredictable when form breaks down late in a race. For a sub-3 marathon (6:52/mile), you need a shoe that rewards your cadence and midfoot strike *and* stays composed when you're tired at mile 18+.
Here are my top picks:
**Puma Deviate Nitro Elite v4** — Best overall for your sub-3 attempt. This is the shoe I'd grab if I were you. It's lighter (170g) and poppier than the New Balance SC Elite v5, with a firm-but-snappy ride that reviewers compare to the NB v3 — meaning it's responsive without being twitchy. Doctors of Running called it one of her favorite racing shoes of 2026, and FORDY RUNS rated it his fastest marathon shoe for confident, faster runners. The 8.0mm drop matches your midfoot strike, and the ride stays consistent through fatigue. It's also $250, which is reasonable for a super shoe.
**ASICS Metaspeed Sky Tokyo** — The refined Sky+ you already know. This is genuinely better than the Sky+ — lighter (159g), bouncier FF Leap foam, and the plate sits higher for more forefoot pop. The Run Testers preferred it over the Alphafly 3, and Kofuzi ran it through 100 miles with consistent ride quality. *But* — and this is important — it's still a soft, poppy shoe that demands form retention. Given your experience with the Sky+, this is a "only if you want to revisit that ride" pick. It's excellent, but not a safer choice than the Deviate.
**New Balance SC Elite v5** — A more forgiving alternative if you want stability without sacrificing speed. Kofuzi calls it "poppier and more race-ready" than v4, and Doctors of Running rates it the most comfortable super shoe for marathon distance. It's slightly heavier (201g) and has a wider fit, but the aggressive rocker and stiffened carbon plate stay predictable even when you're tired. Less exciting than the Deviate, but more bulletproof.
**Saucony Endorphin Elite v2** — The wildcard. Exceptionally soft and springy with unmatched energy return — Kofuzi ran it through 100 miles with consistent snap. But it's also the least stable of this group, and reviewers note it demands good form. Given your Sky+ experience, this could either be perfect (if you love that soft bounce) or frustrating (if softness made you feel unstable when fatigued). Only pick this if you actively want maximum cushioning and bounce.

<summary><strong>Why the Deviate Nitro Elite v4</strong></summary>
The Deviate v4 is the sweet spot for your profile. You're a cadence runner with a midfoot strike, and this shoe rewards both: the 8.0mm drop and firm-but-snappy NITROFOAM Elite midsole make it easy to maintain turnover, and the carbon plate engagement is direct without being unpredictable. Doctors of Running's comparison to the NB SC Elite v3 is key — that's a shoe known for being responsive *and* composed.
Critically, reviewers note it stays consistent through fatigue. FORDY RUNS called it his fastest marathon shoe for confident runners, and The Run Testers rated it one of their top carbon-plate race picks. At 170g, it's light enough to reward your cadence but not so minimal that it feels unstable when form degrades.
Price is also solid at $250 — $35 cheaper than the Endorphin Elite v2, and it's more versatile than the Fast-R Nitro Elite v3 (which is too aggressive and narrow for a marathon).

**One follow-up:** How do you feel about firm vs. soft rides? The Deviate is firm-but-snappy (not plush), whereas the Endorphin Elite v2 is exceptionally soft. If you loved the responsive, slightly mechanical feel of the Sky+, the Deviate will feel more natural. If you prefer maximum cushioning and bounce, the Endorphin Elite v2 might be worth the risk despite the stability tradeoff.
user: I love the ride of my training speedier shoe, Adidas Evo SL. I would like something close to that experience, perhaps?
assistant: Good intel — the Evo SL is a fantastic speedwork shoe with that soft-plush, aggressive rocker ride. The challenge is that the Evo SL is a nylon-plate trainer, not a carbon racer, so there's a meaningful jump in aggression and stiffness when you move to a super shoe for marathon racing.
That said, I can point you toward shoes that *bridge* that gap — carbon racers with softer, more forgiving rides that won't feel as jarring as, say, the Fast-R Nitro Elite v3.
**Saucony Endorphin Elite v2** — Closest to the Evo SL's soft-plush character. This is exceptionally soft and springy with a forgiving, cushioned ride that reviewers compare to a "fun" racer. It's 201g (heavier than the Evo SL's 235g, but that's normal for a super shoe), and the incrediRUN foam is wildly compressive — EDDBUD measured it at Shore A11, one of the softest foams on the market. The trade-off: it's the least stable of your options, which given your experience with the Sky+ feeling twitchy late-race, could be a concern. But if you loved the Evo SL's plush feel and want to carry that into race day, this is it.
**ASICS Metaspeed Sky Tokyo** — Your refined Sky+ experience. It's lighter (159g), bouncier, and more responsive than the Sky+, with better consistency through fatigue. Kofuzi ran it 100 miles and called the ride "consistent" — that's the opposite of your Sky+ experience. The 5.0mm drop is lower than the Evo SL's 7.0mm, so the geometry is a bit different, but the dual-foam setup (FF Leap + FF Turbo Plus) has that soft, springy character you like. The risk: it's still a soft shoe, and softness was part of what made the Sky+ feel unstable when you tired.
**Puma Deviate Nitro Elite v4** — The middle ground. Firm-but-snappy (not plush like the Evo SL or Endorphin Elite v2), 8.0mm drop matching your midfoot strike, and reviewers consistently note it stays composed through fatigue. Doctors of Running compared it to the NB SC Elite v3 — responsive but grounded. It's the safest pick for a sub-3 marathon where form retention matters, but it won't feel as cushy as the Evo SL.
<details>
<summary><strong>The real tension here</strong></summary>
The Evo SL's appeal — soft, plush, aggressive rocker — is partly *because* it's a trainer with a nylon plate, not a carbon racer. Carbon racers are inherently stiffer and more mechanical. You can find soft carbon racers (Endorphin Elite v2, Metaspeed Sky Tokyo), but they sacrifice stability. You can find stable carbon racers (Deviate v4, SC Elite v5), but they're firmer.
For a sub-3 marathon where fatigue will test your form, I'd lean toward the **Deviate Nitro Elite v4** — it's the best compromise between responsiveness and composure. But if you're willing to accept the stability trade-off and trust your form to hold up, the **Endorphin Elite v2** will feel closer to the Evo SL's plush character.
Which matters more to you: that soft, cushioned feel, or confidence that the shoe will stay predictable when you're tired at mile 18?
