Cost me a tooth last summer.
JJ is right about the thrill of controlling big forces with small movements.
It wouldn't be thrilling without the chance of it going wrong.
I'm thinking that the energy stored in the boots as you compress at the apex helps pick you back up as you (carefully) release.
I have two pair of Atomic B Tech boots for my ultra wide feet.
One is 90 flex and one is 120 flex.
When it is warm the 90 flex ones feel like I could telemark in them without pivoting bindings and don't help at all at the end of the turn.
At least that's my story until somebody like Jamt or Atomicman convinces me I'm wrong.
A 30 year career as a professional engineer has taught me the value of being willing to change a theory if better data becomes available.
This ain't religion!
I think one equipment upgrade that I would be willing to pay a lot for is boots that don't radically change their flex with temperature.
My old magnesium Daleboots controlled the flex with steel springs and I loved that aspect of their performance.
Fit?....not so much!
