assistant: Before I narrow this down, I need a couple of quick details to make sure you get the right shoe: 1. **Body weight & footstrike** — Are you a lighter runner (under 150 lbs), average (150–180), or heavier? And do you naturally land on your heel, midfoot, or forefoot? 2. **Super-shoe experience** — Have you raced in a carbon-plated super-shoe before, or would this be your first? 3. **Current shoe** — What are you training in now, and how does it feel? These details matter for a sub-3 marathon attempt because the right super-shoe depends on your biomechanics and whether you need a confidence-building familiar platform or can handle a more aggressive, unfamiliar ride on race day.

assistant: Got it — forefoot striker, heavier weight. That's crucial for a sub-3 marathon shoe. One more detail: **Have you raced in a carbon-plated super-shoe before?** The reason I ask: forefoot strikers tend to feel super-shoes differently than heel strikers, and heavier runners need shoes that won't feel mushy under load. Some super-shoes reward aggressive, familiar plate feel; others need a few miles to settle in. If this is your first super-shoe race, that changes whether I'd recommend the most aggressive option or something with a bit more forgiveness built in. Also, **what's your typical race-day cadence?** (Turnover around 160, 170, 180+ steps per minute?) That helps me gauge whether a lower-drop shoe like the Mizuno will feel natural or require adjustment.

assistant: Good question — and honestly, the retrieval is thin on explicit heavy-runner validation for these super-shoes. Here's what I can tell you: **The New Balance SC Elite v5** is your best bet from this set. Doctors of Running specifically calls it "one of the most comfortable" super-shoes and notes it's a contender for first-time super-shoe buyers — that comfort margin matters for heavier runners who need shoes that won't collapse under load. The full-length PEBA FuelCell midsole is proven durable, and the 8.0 mm drop + moderate rocker will feel stable for a forefoot striker. It's also the widest in the forefoot of these options, which helps with impact distribution. **The Mizuno Hyperwarp Elite** is the lightest shoe here (170g) and has the lowest drop (3.5 mm) — that's aggressive for a heavier forefoot striker on race day. It's excellent if you've got super-shoe experience and a naturally quick cadence, but it's a riskier first super-shoe pick for your weight class. **The Nike Alphafly v3** splits the difference: proven cushioning, excellent lockdown, and a balanced rocker. It's a solid marathon shoe, but I don't have detailed reviewer notes on how it handles heavier runners specifically. The Saucony and Puma cards are too lean for me to assess durability under your load. **My honest take:** The SC Elite v5 is the safest sub-3 marathon choice here because it's explicitly praised for comfort and stability without sacrificing speed. But I'd want to know — **do you have access to a running specialty store where you can try these on?** Super-shoes are expensive enough that fit and feel under *your* weight matter more than generic reviews. If you can't try them, the SC Elite v5 is the pick.
