1000 mile Fusion Double Layer Socklet The Men’s Fusion Double Layer Socklet is knitted to a trainer liner length profile, for those who prefer a ‘no sock’ look. We use the same double layer technology with the blister free guarantee. It has padded zones in the toe area and ball of the foot for comfort and protection. Ventilation mesh on the top helps to keep your feet cool. Double layer sock reduces friction helping to prevent blisters.
