Adidas Trionda World Cup ball tested; flight dynamics and surface raise concerns

The Adidas‑produced Trionda, selected as the official ball for the 2026 FIFA World Cup, has undergone testing that details how it will fly, dip and swerve during the tournament.

Simulations of the ball’s unique four‑panel design indicate that its relatively rough surface could cause long kicks to fall a few metres short of their intended targets, raising concerns among scientists and players about its performance characteristics.
