you can do a number of things depends on what your doin in the park many pro riders like to tune their skis like a park snowboard with a variable bevel, 1 degree at tip and tail and fluxuating to a 2 or 3 degree under foot where you'd slid rails.
or you can just pull the edges and roll them under foot like thall does. on the pipecleaner.
some even cut out there edges under foot and lay in platics so that they slide quicker
in the end everything works for each their own but as a tech my self i would typically just ride them till they're good.
