assistant: Great — sub-3 is a serious goal and your mileage + midfoot strike give us real data to work with. One quick clarification before I lock in picks: **Have you raced in a super-shoe before, or will this be your first?** That matters for stack preference and plate aggression. In the meantime, here's the lay of the land: You've got three standout options in my data, each with a different philosophy. **Mizuno Hyperwarp Elite** is the speed-first pick — lightest shoe here at 170g, lowest stack (39/35.5mm), and a low 3.5mm drop that plays to your midfoot strike. Firm-responsive PEBA foam and a 3D carbon plate built for pure racing efficiency. Best for runners who want minimal cushion and maximum responsiveness. **Nike Alphafly v3** is the all-rounder — balanced ZoomX foam with forefoot Air Zoom units, excellent lockdown, and a moderate rocker that suits marathon pacing without sacrificing speed. 198g, true-to-size fit, and reviewers note it handles both race-day and long-run work. Doctors of Running and The Run Testers both rate it highly for marathon distance. **New Balance SC Elite v5** leans comfort-first for a racer — wider toe box, stretchy upper, and Doctors of Running calls it "one of the most comfortable super shoes" and a contender for super-shoe of the year. 201g, 40/32mm stack, full-length PEBA plate. The Run Testers notes it's "still relatively stable" despite the aggressive update. Trade-off: not the fastest, but durable and forgiving over 26.2 miles. **Puma Deviate Nitro Elite v4** has excellent expert reception and sits at $250, but my data on it is lean — I have specs and category but no detailed reviewer notes to guide fit or ride character for your midfoot strike. Once you tell me about super-shoe experience, I can narrow this to your top pick.

assistant: **Alphafly v3** — for your sub-3 marathon. Here's the split: The **Vaporfly 4** is a 5K–half-marathon specialist. It's lighter (167g vs 198g), lower stack (36/30mm), and built for shorter, faster efforts where you're running closer to VO₂ max. The durability spec flags it too — "low miles" means the foam breaks down faster, which matters less over 13 miles but becomes a real problem over 26.2. The **Alphafly v3** is purpose-built for marathon distance. The Run Testers calls it a "superbly bouncy marathon racer that protects the legs well while still being very fast" — that leg protection matters at mile 18 when glycogen depletes. It's got more stack (40/32mm vs 36/30mm), the forefoot Air Zoom units add responsiveness without sacrificing cushion, and the moderate rocker suits marathon pacing. True-to-size fit, excellent lockdown, and reviewers note it handles both race-day and long-run work. One caveat: FORDY RUNS warns that the soft ZoomX foam can overwork calves and cause cramping late in a marathon for first-timers in super-shoes. Since you didn't answer whether you've raced in a super-shoe before — if this is your first, you might want to log 2–3 long runs in the Alphafly before race day to dial in calf loading. If you have super-shoe experience, you're golden. The Vaporfly is a weapon for a future 5K or half-marathon goal, but for sub-3 marathon, Alphafly wins.
