Light as a feather.
I'd like to start off by saying if you have never bought 686xNewBalance boots dont be hesitant. These boots are true to size and are very comfy. When I first put them on I was in awe, they were hands down some of the lightest boots I've ever put on my feet. When I walked around it was as if I was wearing shoes... yet the boots do not sacrifice stiffness for weight. Go get yourself a pair!
