Adidas Adizero Adios Pro 4 vs Asics Metaspeed Edge Paris:
Which to Choose

Start with the specs, because they're remarkably close: both sit on roughly a 39mm heel stack (39mm heel/33mm forefoot on the Adios Pro 4, 39.5mm/34.5mm on the Edge Paris), both run a low race drop (about 6mm versus 5mm), and both pair springy PEBA foam with a carbon propulsion system. Weight is the first concrete separator — the Edge Paris is the lighter shoe at around 185g versus roughly 201g for the Adios Pro 4 (men's size 9), a gap you can feel over the back half of a marathon. The bigger difference is the plate itself and the foam tuning. Adidas uses segmented carbon-infused EnergyRods under a dual-layer Lightstrike Pro midsole, which reads as softer, livelier and more aggressively bouncy, with a pronounced rocker that actively tips you forward and rewards a surging, forward-driving style. ASICS runs a full-length carbon plate under FF Turbo Plus foam tuned deliberately firm; the Edge feels more connected to the road and more locked to a single rhythm, which is exactly its design intent — it's built for "strength" runners who hold an even, powerful cadence rather than those who float and change gears. Use case narrows it further: the Adios Pro 4 is rated from 10K through the marathon and will come alive at shorter, faster efforts, while the Edge Paris is a dedicated half-and-full specialist. On durability and grip, the Adios Pro 4 has a Continental rubber outsole that bites well in the wet; both use thin, breathable race mesh uppers and share the same caveat — tall, narrow, neutral platforms that feel tippy at jog pace and demand attention on corners, so neither is remotely a daily trainer.
