Where do you stand?

  • Shins and legs parallel

  • Skis at same edge angle

  • Balanced fore/aft

 

 

 

 

 

 

 

Tracking:
The direction that the knees flex

 

 
Where do you stand?

  • The feet hold the skis on edge
  • The feet articulate to fine-tune edging and balance

 

 

 

 

 

 

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

 

 

 

 

In-boot alignment

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?

What's your foot type?

"Normal foot"    
  • Upright heelbone
  • Average range of motion
  • Stable when weighted
  • Strong lever with flexibility
    

 

What's your foot type?

"Normal foot" "Rigid, high-arched foot"  
  • Upright heelbone
  • Average range of motion
  • Stable when weighted
  • Strong lever with flexibility
  • Heelbone rolled toward outside
  • Little or no range of motion
  • Very strong lever
  • Little finesse or articulation on edge
  

What's your foot type?

"Normal foot" "Rigid, high-arched foot" "Flexible, overpronated foot"
  • Upright heelbone
  • Average range of motion
  • Stable when weighted
  • Strong lever with flexibility
  • Heelbone rolled toward outside
  • Little or no range of motion
  • Very strong lever
  • Little finesse or articulation on edge
  • Heelbone rolled toward inside
  • Large range of motion
  • Weak lever

Types of Footbeds

  • Rigid
  • High-density
  • Soft

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

Compressible Arch Support

Harb Ski Systems footbed benefits

Individualized to shape and biomechanical needs

 

  • Hindfoot support angle

  • Forefoot to hindfoot angle

  • Arch height

  • Flexibility

Non-optimal alignments

 

  • Bowlegged and knock-kneed

Results...

  • Harder to roll skis on or off edge
  • Difficulty with edge grip - too much or too little
  • Joint stress
  • Inefficiency
  • Asymmetry

 

Non-optimal alignment:

Non-optimal alignment:

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.

 privé-skileraar nodig?

Zeer vriendelijk, ook een uiterst bekwaam telemarkskiër of gids voor het gebied.
