K-Swiss Ultra Natural Run II S Review
The Ultra Natural Run II S from K-Swiss is a new ultra-lightweight performance training and racing shoe. K-Swiss classifies this as a stability shoe with guidance provided by their GuideGlide Guidance System™, but our testers felt that this cushy, minimalist shoe might be better suited to lightweight neutral runners. The midsole is composed of Superfoam and k-EVA and provides a very soft cushy ride for a stripped-down shoe. The midsole and outsole also sport drainage holes making this a great shoe for triathletes looking for water drainage and ventilation. Some of the upper reinforcements are somewhat stiff, but seams are minimal inside the shoe and comfort is great after a short break-in.
Overall, we feel that the K-Swiss Ultra Natural Run II S is a great cushioned performance training and racing shoe for runners looking for a fast and light shoe for tempo runs and racing. For more information, please visit kswiss.com.
