Waar sta je?
- De voeten
houden de ski's op de kanten.
- De voeten
regelen de juiste hoek en de balans
Articulating
the foot
The
feet must be able to tilt on and off edge
Where
do you stand?
Optimal
in-boot alignment yields:
-
Symmetric
angles
-
Parallel
legs
-
Skis that
work in unison

Feet
& Footbeds
-
The foot
is your base of support
-
Some feet
need "help" to ski well
-
The footbed
sets up your foot to ski well
-
It should
meet the mechanical needs of your feet
-
Considerations
are support & articulation
Is
your foot good for skiing?
-
Can
it roll your skis on and off edge?
-
Can
it hold your skis on edge?
-
Does
it absorb vibrations to keep the skis tracking?
-
Can
you adjust your balance and edging with subtle foot movements?
-
Is
it comfortable?

Arch
Support
-
The arch
must be able to flatten for the foot to help in edging
-
The footbed
arch should yield under pressure from the foot
-
The footbed
material should "spring back" when the foot stops
pressing on it

Stand
Corrected!
Een juiste stand op de ski's geeft veel meer
skigevoel en veel rust tijdens het skiën.
Er wordt direkt gevoeld wat de ski doet en daar
kan dan direct op geanticipeerd worden.
Portes Du Ski is de enige in Nederland waar deze
kennis en dit materiaal aanwezig is.
