The Jingtan 4.0 is BMAI's flagship carbon racing shoe: firm and responsive, demanding leg strength and a mature gait, and the carbon feels stiff at slower paces — not for brand-new runners, but once you have a racing base it shines in speed sessions and on race day.

User Review Summary
The BMAI Jingtan 4.0 (2026, unveiled in Hangzhou) is BMAI's flagship carbon-plate racing shoe, an upgrade built on the Jingtan 3.0 TURBO. The midsole uses nylon-billet supercritical foam from Evonik feedstock, combining energy return with light weight, and the 31mm forefoot / 35.5mm heel stack with a 4.5mm drop is a proper high-performance racing setup. The platform is widened from front to midfoot to heel with a thicker sidewall to optimise force transfer, so a racing shoe can 'run fast yet stand stable'. The centrepiece is an upgraded T1000 full-length carbon plate with reinforcement ribs, stiffer than the previous T700, giving sharper push-off and propulsion. The race-grade PU polyurethane outsole has optimised starburst-particle density and orientation for greater groundbite and enhanced water drainage, lifting wet-ground grip and rain performance. The lightweight kite-gauze upper pairs with an integrated knit sock tongue and a wide Chinese foot shape (wider forefoot, higher instep) to ease pressure on wide feet. At only about 172g (EUR41), it sits in the top tier of flagship carbon racers — for advanced and elite runners chasing PBs.
