The Ultra DNA Fluo Yellow/Black Out from the brand Dynafit is a unisex trail running shoe designed for ultra-trail competitions and long distances. Weighing 280 g with an 8 mm drop, it combines lightness, dynamism, and comfort to support prolonged efforts on the trails.
Its SPEED+ midsole promotes a smooth and dynamic stride thanks to its excellent energy return. The Vibram® Litebase outsole with Megagrip rubber and 4 mm lugs ensures good grip on various trail surfaces. The Rockshield technology also enhances foot protection against irregularities and aggressive terrain elements.
The Double Speed Lacing system allows for precise and even adjustment of the foot.
