What's the point of a gearbox?
If you're between 2 sizes, or your boots are too tight, or you feel your foot moving around in the boot,
This 3mm reducer raises your foot in the boot, reducing the internal volume of your ski boot.
This device looks very simple, but it's very effective.
If the volume of your boot is really large, you can superimpose 2 reducers.
Which size to choose?
This 3mm reducer comes in 2 sizes: 35/41 and 41/47.
Simply choose the size range. If you're a size 41, take size 41/47.
