As has been said go get fitted,
but the new ones may be a little soft for you, there only a 100 flex. I got some last season and there quite soft. You may be better looking for last seasons SPK Pros as they are a 110 flex. Or you could look at the ghost if you want to keep with salomon, but they fit very very differently.
So really go get fitted, without a boot in mind and buy what fits the best and what the fitter recommends.
