The Rollerblade Tempest 100 Inline Skates were designed for the fitness skater that wants to improve and strengthen their skating. Rollerblade created the Tempest 100 specifically for men. The boot is soft and made of a fiber tech shell to provide you with durability along with a superior fit like no other. Fast, smooth and effortless is what you will experience each time that you take to the road, track or surface to begin your cardio pumping distance skating. The extruded aluminum frame is tough, stiff and durable, allowing you to skate farther, faster and easier with less effort. The boot closure consists of a cuff buckle, 45 degree power strap and performance asymmetrical lacing for a precise and custom fit each and every time you strap them up. The SG9 bearings will determine the smoothness of your ride and your ability to reach higher speeds with less effort, thus creating a longer roll for you to use to your advantage. The liner consists of a precision five star fit that is made of memory foam and anatomical pads that are lighter in weight and allow for your feet to remain much cooler on those long distance training days. This low profile boot with the 45 degree strap and high end components will be the essential part of your inline skating while providing you with support around your ankles for lateral movements that are key to your cardio pumping workout.
