Designed and built for the serious fitness skater looking to strengthen their skating, and participate in advanced fitness training activities. Rollerblade has created this pair of Tempest 100 Inline Skates just for women. This soft boot is made of a fiber tech shell to provide you with durability along with a superior fit like no other. The extruded aluminum frame is tough, stiff and durable, allowing you to skate farther, faster and easier with less effort. A stiffer frame has less flex and movement, this reduces the amount of energy that is lost when energy is transferred to the spiral HP wheels. 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 and maneuverability that are key to your cardio pumping workout.
