Contragrip® MA  The Contragrip® MA sole is perfectly balanced for the widest variety of surfaces. It combines the geometry and the rubber compound to deliver confidence on wet, dry, hard or loose surfaces. Optivibe™ To reduce vibrations as you run, the shoe uses Optivibe™ technology which specially combines foams – one to dampen and one to propel. This is designed to decrease muscle fatigue without affecting the overall ride. Profeel Film The integrated Profeel Film filters out rocks and sharp surfaces for enhanced comfort and stability. Single Layer Mesh A single layer of mesh is used, close to the foot, for maximum comfort and breathability. Water Repellent The shoes are treated with a special water repellent treatment that prevents the fabric from absorbing water during light rain and showers. EndoFit™ The interior of the shoe comes with an EndoFit™ sleeve which is designed to hug the foot in exactly the right places to provide a tailored feel. Welded Upper The upper is welded instead of stitched to deliver a smooth, glove-like fit and feel. SensiFit™ On the inside of the shoe the SensiFit™ layer cradles the foot from the midsole to the lacing system which provides a secure, snug and virtually customised fit all around the foot.
