both equipped with BTS. I did not try Le Mans, but my indys are very flexible....and even if Le Mans with switch have same flex as indys with BTS i would prefer last one because they work correctly and bend. LeMans are working like softboots and crumple.
Jacques was already modifying his boots in the eighties!Viviane wrote:Question to J & P:
I am reading and hearing a lot about the flex modification on our boots.
(p.e. BTS Deeluxe)
Did you modify your boots?
I remember clearly how he modified the first alpine snowboard boots: the famous model form Raichle which was green and white. I benefited a lot from Jacques' excellent (and avant-garde) ideas. 
We also modified the following models from Raichle, then the Blax model (which became the Head model). In 1997 or 1998 we bought the Northwave 900. Our modification was published in 2002 here (look at the picture of the boots).
We are glad to see that many riders now modify the original springs of their boots. Some manufacturers and individuals have even started to produce and sell ready to use kits.It has been the key to the development of our "push-pull" technique (and extremecarving in consequence). The "avalement", as discussed recently here, is crucial.Viviane wrote:Is it really necessary?
Hardly. At racing however you need stiff boots. It's different. As always, all depends on what you want to do.Viviane wrote:Is it impossible to bend your knees enough without them?
The flex is higher to the front than to the back of course. Look at the pictures: there are 2 springs. A long one (sometimes a series of 2-3 springs) for the flex to the front, and a short (and hard) one for the backwards move.Viviane wrote:Does the eventual spring modification give your boots more fluently flex to the front as well as backwards?
Or is it fixed in a more frontal position?
