Yeah, every once in a while I'll pick them up and they feel like bricks. But I did my best skating and the best years of playing were spent in them. If anything, I have weak ankles now because the support of composite boots.
Just not for me, I returned them. Perhaps its just me, not giving it enough time but I just don't have the patience to get adjusted to it. Doesn't help that public skating near me is 16.50 to 18 bucks a session now.
They really ought to find a way to channel the success of the 703 into modern tech. They don't need to radically alter any of the major function points, just upgrade the construction. That's proven tricky over the last few decades, however.
