These have much more flex all around, including laterally, than the softest BTS springs allow with the T700 boots. I never rode them because the cuff seemed too low, but I never had a soft pow board before. When I took them out on the Nomad on a gentle nearby hill, I liked the flexibility. In comparison, the T700's are so stiff that in super soft conditions, like deep powder, that I can't flex my legs and shift my weight to absorb terrain changes without also applying too much pressure to the board.
I was wondering if the Raichle 123's, or some of the other softer hard boots recommended, have a higher cuff than the Burton freecarves?
