Ski Boot Insoles

The guy in this vid seems to advocate replaceing the "cardboard" insoles your boots were sold with. Is this in reality a standard decent purchase?

For most people, yes. But You can do this in degrees, An off the shelf orthodic foot bed designed for skiing is a step up. But even these may require some expert advice, as what feels OK in the store maybe too much (or in the wrong place) arch support in a ski boot (read pain).

Best to do a lot of research, or bite the bullet and go see a good boot fitter.

the best thing I ever bought was some properly moulded footbeds

Not everyone needs them. That said I did and as above prob the best thing I've spent money on for skiing, all I would say is make sure the guy making them knows what he's doing and uses heel stabilisers etc

I use these - Sorbothane Sorbo-Pro Total Control Insoles

In my ski boots, walking boots, work boots and things.
I have a funny problem on the ball of my left foot that means it needs some support and these work brilliantly.
Very supportive foot bed and a sensible price too.

putting something in the boot rather than the stock "cardboard" is the best way to ensure a great fit, the footbed is the foundation of the fit, you wouldn't buy a house that had no foundations so why ski without a foundation under your foot..... as you ski you apply pressure form edge to edge, your feet roll to do this, if there is no support then the arch of the foot has to collapse until it either hits the bottom of the boot or the muscles reach the end of their elastic travel before you can edge the ski, the footbed will fill the gaps and allow a much more dynamic transition from edge to edge and reduce a load of the fatigue that can come from skiing without.... the key is not how much or little you can pay for them, but if they are off the shelf that they are the best ones for YOU and if they are custom made that the guy/gal making them really knows the foot and the product and can select the correct thing for you, for example avoid 1 product fits all, in my store we have 5 custom products from one brand and an infinitely adaptable (in terms of density) product form another brand....different feet need different solutions

I have moulded foot beds in my boots and they are an amazing fit. But I have problems with shin splints in the last 2 years and also I've torn ligaments in my left ankle twice in the last few years through sport, so I've used orthotics and various different supports. The best ones that I've found are from this site http://www.drfoot.co.uk/ they a are a little pricey but well worth the money if you have an injury or for general support. I couldn't recommend this site enough as you can find what your after by looking by injury or problem.

Have you really got cardboard insoles in your boots?

Or have the stock insoles been removed and not replaced?
