The Geo Racer Knit is VIVOBAREFOOT’s lightweight trainer designed for “barefoot feel + everyday functionality.” It features a recycled PET knit upper with excellent breathability and flexibility, making it ideal for gym workouts, bodyweight training, and short-distance jogging. With an outsole of only about 2 mm, no midsole, and a zero‑drop design, it delivers full ground feedback, helping activate foot muscles and improve gait awareness. The wide toe box follows the natural foot shape, making it suitable for wide feet and flat‑footed users. Testers report that the Geo Racer Knit provides stable ground contact during squats and deadlifts, though it’s not recommended for high‑impact activities or long‑distance running. If you’re looking for a training shoe with barefoot feel, breathability, and everyday versatility, the Geo Racer Knit is one of the lightest and most flexible options in the VIVOBAREFOOT lineup.
