assistant: The **Brooks Hyperion Elite MD v2** is a track-specific spike shoe, not a road racer — it's built for the oval with a 6-pin spike plate, not road racing. That said, your sub-19 5K pace and neutral biomechanics put you squarely in the super-shoe zone, and you'd absolutely benefit from a carbon plate for road 5K/10K. I only have this one shoe in my current data, which is a catalog gap on my end — I don't have road racing flats or super-trainers for your pace and distance. Before I can give you solid picks, I need one clarification: **Are you looking for a dedicated carbon-plated racing flat** (minimal cushion, ~150–200 mi race-pace life, worn primarily on race day), **or a super-trainer** (more cushion, carbon plate, 300–400 mi life, usable for both race day and some training)? That distinction will point me toward the right shoe category for your goals.

assistant: For a sub-19 5K on the road, the **Saucony Endorphin Pro v5** is the clear winner here. It's a full-featured road racing super-shoe with a carbon plate, aggressive rocker, and PEBA dual-layer midsole (39/31mm stack) built for exactly your pace and distance. True-to-size fit, good lockdown, neutral geometry — it checks every box for a 5K/10K racer. The **Brooks Hyperion Elite MD v2** is a track spike shoe, not a road racer. It's minimal-cushion (156g, DNA GOLD PEBA) with a top-loaded carbon plate *plus* a 6-pin spike plate for the oval. It's a different animal — built for 1500m–5000m on the track, not road racing. If you're running road 5K/10K, this isn't your shoe. **The pick:** Endorphin Pro v5 for your road race-day needs. Its mixed expert reception is worth noting — some reviewers find the ride polarizing — but for your neutral biomechanics and sub-19 pace, the carbon plate and aggressive rocker are exactly what you want. Stack height (39/31mm) sits at World Athletics' road-race ceiling, so you're getting maximum foam and energy return within the rules. One follow-up: Have you raced in a carbon-plated super-shoe before, or is this your first?
