This Or That Sneaker Split

Hard vertical split-screen with a fixed center divider; left half cool-grey concrete, right half warm-toned hardwood. 0-2s: identical low-angle shots of two feet — left in a generic scuffed canvas trainer, right in crisp [product] performance runners — both planted at the start line, still. 2-4s: synchronized push-off; left foot lands flat with a dull heavy thud and a puff of dust, right foot rolls heel-to-toe as the foam midsole visibly compresses then rebounds in crisp slow motion. 4-6s: the divider slides left and the right side floods the frame for a hero tracking shot of the runner mid-stride, knit upper flexing and laces snapping taut in directional rim light. Punchy high-contrast lighting, gym-floor squeak and a springy impact thump. Both shoes hold consistent silhouette, tread pattern, and colorway across every cut — no deformation, drift, swapped sides, or artifacts.
