Already adopted by runners worldwide, our latest generation running sock receives a seasonal upgrade to help you stay bright and safe in low-light conditions. Combining optimal aeration and blister-protection with fluoro yellow highlights and reflective details, the PRS Run High Flash socks are ready to hit the road running. The technical weave is lightweight and ventilated, quickly wicking away moisture so your feet remain fresh and dry. The ergonomic toe box offers a perfect fit and improved proprioception, allowing the toes to grip intuitively on landing for a natural, fluid stride. A special knit around the ankle offers targeted support when you pick up the pace, while terry cloth padding on the big toe saves you from blackened nails on longer runs. The medium arch support boosts micro circulation and prevents the fabric from twisting and folding, saving you from painful blisters and irritation. Underfoot, a pattern of 3D.Dots (75%) and Flat.Dots (25%) cushions impact and offers added grip, ventilation and light micro stimulation to increase venous return and delay fatigue as the miles build up. A line of high-viz yellow 3D.dots up the Achilles tendon are sandwiched between two rows of Flat.Dots for added support and ventilation. Four bands of reflective yarn around the calf and a reflective rear logo light up in headlights to ensure your feet quite literally flash as you run. The height of the Run Sock is lower than the trail and bike models, with a fit and technologies that are specifically designed for the demands of road running. An ergonomic tab at the back adds a touch of comfort and style and, should you forget which activity you’re heading out the door for, the discipline is discreetly embroidered on the inside. From extra speed to extra visibility out on the road, this high-tech sports sock ensures nothing is left to chance.
