deep wax saturation and dense circular braiding impart the necessary torsional rigidity to ensure the lace stays completely flat across the tongue.  Handling & Edge Guidance    Swipe horizontally WidthModel SeriesGuiding Technique & Eyelet DynamicsAvailable LengthsRecommended Shoe Style3.0 mm FlatDelicate LaceF3-CS (3 mm)Glides smoothly through narrowly pierced blind eyelets;
