The Opal SL is built with Northwave's TF2 advanced liner with it’s Thermo-Fit molding foam which targets the fit zones allowing them to catalyse instantly with a heater or with body heat over an extended period of time. Northwave's Super Lace System allows the closure of two different boot areas - the quarter part and the collar part - in order to allow you to select the perfect feeling on each part and improve comfort and foot stability.
Northwave's Thermo Welding beats the elements, as it provides a seamless outsole. This is particularly important in the ankle zone where there is no interruption of the upper boot technology bringing you, the rider, and progressive support from the heel to the calf.
