For the moment not all boots fulfil the new standard DIN ISO 23223 (Alpine ski boots with improved walking
soles).
Each boot changes between model and size in the shape (nose, rocker, contact zone) and insert. With that
the sole and the contact point with the binding are used.
It is therefore important that the specialist dealer checks every system
boot
– binding
to get an optimised
function using the following method.

TOE AND HEEL
- Rubber sole and metal insert must be flush
with the plastic

SOLE / SHELL
- Minimum space between:
• Ball of foot – binding:
3 mm
pin
1 mm
alpine toe/heel
• Heel – binding
1 mm
- Boot WITHOUT ergonomic bellows
► To get a correct release
NOSE OF BOOT
- boot has enough walking angle
(min 70°)
- Binding must release the boot at the front
► To get an optimised walking comfort and/or that the binding releases the boot correctly after a
frontal fall
FIXATION
- Inserts are held by the pins without any
clearance or friction
- Enough edge as interface area (min 6 mm)
to hold the boot tight
► To get a confident grip and ergonomic movement and a defined release
We recommend using a ski binding adjustment and testing equipment according to DIN ISO 11110.
