SGS has been around for a few years now.
The SGS boots I have seen have all been pretty darn heavy because the shell has to be separately rigid from the toe & heel-lug rail. They have all been COLD because of conductive heat loss from that great hunk of aluminum bolted on underneath. And, worst for some, not so much for others, the boots I've seen were high volume buckets made for H shaped, not V or I shaped, feet.
Further, the best information I have is that the original SGS was recalled because the lateral adjustment could slip and that the modified versions all have not 2 bolts but 3 on the adjustment rail.
I'd agree with kwillg6
, with the proviso that someone with knowledge probably wouldn't need the SGS system.
Fischer + Salomon? Interesting.
