"H.W. Stockman" wrote So, does
rollerblading do anything to improve skiing skills?

Yes they do. While technically correct, racing style rollerblading is not a
very downhill skier specific motion, it does improve quad and calf strength
and overall cardiovascular fitness.

Moreover, you can easily design for yourself blade based exercises that
improve one-footed dynamic balance, kinetic timing and reaction and the
effectiveness of proprioceptive signalling. All of those will translate
rather directly into better downhill skiing, whether telemark or alpine.

For example, try rolling on a single foot, weaving from side to side by
angulating at the hip.

Loosely tied skates will work your ankle strength and responses more.
Loosen the top laces and practice knee bends while rolling. Do the same
thing one-legged.

A free style skate, rather than a racer or one built for long miles, will
require more fine motor adjustments. Be creative and be aware that most
pavement is harder than most snow.
