I too am in the market, and curious about Salomon Calibers. Yes, they are canted.
However, they are also quite expensive... Through my research, and personally checking out some alternatives, I thought that Forum Shakas and Ride Capos were nice and stiff - and they both have canted footbeds as well. The nice thing about the Capos is that you have the option for Super canting with 4 degree footbeds.
The Shakas strong point is the simmer down tech. Basically, the footbed only cants as much as you naturally need it. Takes the guess work out of it.
I still haven't decided, but both the Capos and Shakas seem to provide the same amount of support, and I am finding them for about $100 less than the Salomons right now.
