In reply to ligemidio:
i'll echo exactly what chris said, but ask you further questions....
where are you snowshoeing? are you snowshoeing just for the experience or is there a further objective?
are you snowshoeing in technical terrain?
do your crampons fit your board boots?
make sure everything is adjusted and fits before venturing out.
i see snowshoes as a tool to travel though the mountains in deep snow when for various reasons the skis aren't suitable, and so match my boots to the final objective - they all (including mantas & cumbres) seem to work reasonably well with the snowshoes.
