WHAT IS GRIPFORCE TECHNOLOGY
When you turn the knob on the side of the sole the regular boot transforms, and the cleat-system is activated. The activation allows the cleats to emerge and push down into any ice or snow using the weight of your body. When walking on hardwood floors such as asphalt, the cleats stop at the bottom edge of the sole because your bodyweight can not push them through the asphalt. Therefore, even in ON-mode, you will always have the complete outsole in contact with the ground enough for you to get the traction required by the underlying material. This intelligent and automated system enables you to use the boots on all types of surface materials, always getting the perfect grip.
Gripforce’s world-patented technology enables the spikes to protrude from the sole in on-mode, pushed down by the weight of the user’s body. In off-mode, however, the spikes stay inside the sole. This is possible due to the outsole being either flexible (in on-mode), or rigid (in off-mode). Two worldwide patents protect the technology embedded within the sole.
