Skike V07 Plus Roller Ski Bundle with Free Poles Free carbon-composite poles ($69 value) grip securely on asphalt as well as softer surfaces. Discount available if you don't need the poles. Universal bindings fit all types of shoes and boots. Ski boots are not required. 6-inch inflatable rubber tires give you a comfortable air-cushioned ride. The Skike V07 Plus rolls comfortably on hard-packed gravel and dirt, crushed limestone, and even close-mowed grass, in addition to asphalt and concrete. Built-in emergency brakes on both left and right skis give you an extra safety margin. Please send us a message with your height, weight and shoe size, so we can customize your order. If we do not hear from you, we will size your poles for a 5'4" skier.
