Tuning for your feet! Perfect grip, more performance!
The stable Booster for an increased heel grip in ski- or snowboard boots are super easy to mount.
The system helps you to minimize a "slip out" of your heel.
Simply put around your liner to get more heel grip due to less volume and more stability.
More heel grip = more control!
Small is best for boots 26.5 and smaller. Large is best for boots 27.5 and larger.
