The Sidas Winter+ Slim is a pre-shaped insole for skiing and snowboarding, designed for slim, snug-fitting boots where a thick footbed would take up too much room.
It gives foot support and stability while helping prevent overheating and fatigue. An Ionmesh top cover adds cushioning and is antibacterial, and Transflux C and Podiaflex N reinforcements provide support and stability. Together they keep the foot steady in the boot so more of your energy goes into the ski.
It works great as a ready-to-wear insole, and it can also be customised to your feet in less than 10 minutes with Sidas FlashFit technology by a professional with a FlashFit machine, for even more comfort.
Its low volume keeps the fit precise in performance boots, which is exactly where support matters most. Trim it to match your stock insole for a clean fit.
It is a great upgrade for skiers in tight, performance-fit boots who want better support without losing room.
