Also, the 1K's felt fantastic right out of the box. Very little break-in required. I found the GT's very stiff out of the box. I'm sure they'd break in nicely, but I loved that the 1K's were comfortable from day one. I'm still up in the air about adding a rubber/composite half sole for this winter. We had more snow last year than in the 10 before it. I really like the half soles that can be added to the leather like the Vibram 2341 Raptor: http://www.cobblersupplies.com/servlet/the-106/VIBRAM-2341-Raptor-Rubber/Detail It's not so beefy to ruin the aesthetics of the sleek leather sole but would add considerable grip...esp if you are walking a lot. The Vibram #435 is another option that doesn't seem overkill on a boot like the 1K. http://www.cobblersupplies.com/servlet/the-653/VIBRAM-435-Oil-Resisting/Detail Good luck with whatever you end up with. I'm loving my 1K's.
