If you loved the first series of our anti-blister Pro Marathon socks, you’ll love this updated model too, designed to make your run even cooler and more comfortable. Featuring a higher concentration of PTFE yarn, especially across the whole toe, the fabric of these high-performance running socks is designed to reduce friction, rubbing and overheating during effort, greatly reducing the risk of overheated soles and painful blisters. As well as the non-slip 3D.dots under the foot, they feature an innovative non-slip band behind the arch, specially developed to stop your foot moving inside the shoe and generating heat. Woven in coloured yarn, this band is easy to spot thanks to its contrasting colour, and it will also help you find your new favourite socks in the pile. Our famous arch support creates medical-grade compression to stimulate blood flow and stop the fabric twisting and creasing, while the reinforced heel band provides extra support over long distances. More breathable than ever, the top of the foot and the ankle feature our striped technical knit for maximum ventilation and breathability as the pace and the temperature rise. For pro athletes and for everyone who loves to run, high-performance sports socks are the ultimate answer to overheated soles and painful blisters. So put them on and sign up for the marathon you’ve always wanted to run: we guarantee the only thing smoking will be the stopwatch.
