I've been wearing this boot since 2005.  Another geologist I work with turned me on to them, and I am forever in his debt.

The Georgia Giant is sturdy and well built, but the real selling point is its light weight.  These boots are very light.  Think walking-shoe light. It's the lightest steel-toed boot I've found.

But somehow the designers managed to make it sturdy and supportive.  Just a really good boot.
