Microsoft Copilot (Smart) answer to "best marathon running shoes":

Elite Marathon Racing Shoes:
1. Nike Alphafly 3 ($305) — maximum propulsion, "best overall marathon racer ... most commonly used by elite marathoners."
2. Adidas Adizero Adios Pro 4 ($254.99, 4.7) — best stability-to-speed balance.
3. ASICS Metaspeed Edge ($270, 4.5) — best for cadence runners.

Fast Training / Race-Prep: ASICS Superblast 3 ($210), Saucony Endorphin Speed 5 ($175, 4.5/1.4K).
Budget: generic carbon-plate shoe ($47).

Recommendation: "best overall marathon racer, go with the Nike Alphafly 3."

Brands named (in order): Nike (Alphafly 3), Adidas (Adios Pro 4), ASICS (Metaspeed Edge, Superblast 3), Saucony (Endorphin Speed 5).

Tracked-brand presence: Nike CITED rank 1; Adidas CITED rank 2; Asics CITED rank 3; Saucony CITED (fast training -> position null); Hoka ABSENT; Brooks ABSENT; New Balance ABSENT; On Running ABSENT.

NOTE: Both ChatGPT and Copilot named Nike Alphafly 3 first for marathon. Across surfaces the top marathon-racing picks were Nike, adidas, and ASICS; on this query Saucony was named in the "fast training / race-prep" group rather than the elite-racing group.
