Sidas PU Foam Injected Liners
Foam injected liners provide a precise fit, fully forming to the shape of your foot and lower leg, improving both comfort and performance.
They are an excellent option for those with prominent ankle bones, slim feet and lower legs, or those with unusually shaped feet as the foaming process fills the liner to your foot shape. The liner begins as an empty shell with just the inner and outer layers. Two-part PU foam is then injected into the liner filling the space between the foot and ski boot shell.
This gives a bespoke fit matching your foot. The increase in foothold and the toe construction that can be thinner to a standard liner can help a little with length.
