Any of the skating techniques can be executed with Classic
skis.
Most common is to use a sort of one-sided skate for going
around a curve -- like "marathon skate".
what for
If you're in a situation where your grip wax is slipping on almost
every step anyway, you might as well switch to a technique where the
slipping is a positive objective.
Overall the skating
techniques have several advantages over classic
stride:
(a)
the ski does not have to match speed in static contact with the snow
surface in order for you can push on it.
(b)
by adjusting the angle of the ski to the speed of forward motion, the
big leg muscles can be used in their best speed and force ranges.
(c) easier to smooth the force over time,
maintain momentum.
(d) more effective use of abdominal muscles
in poling.
(e) no grip wax to add friction to slow the
efficiency of the glide phase.
hints
It's tough to skate with waxless skis. For best skating on
waxable skis, use a cold-temperature grip wax.
