This. For all I know, being a creature of habit, that means the skis are always on the same feet. But they get tuned regularly, so I'm not sure it makes a difference. I used to have left and right skis (Dynastars? Salomon's?) so i didn't switch often. People would tell me my skis were on the wrong feet occasionally. But that was a way to save an edge for days I really needed a fresh edge. Nowadays if I'm noticing edge inadequacy, I'll swap hoping for an improvement.hmm, I just put the skis on the ground were they lay and stomp in and ski.
