These are lightweight boots with good support and yet are comfortable. The sole is like the other Keen shoes having an aggressive tread and broad room for your toes. The ankle is well supported. My boots were broken in in a couple of days of wear. I saw the same boots at Scheels for nearly a hundred dollars more. These boots are neither too warm or too cool. They breathe well, and though they are all leather, give adequately to allow for maximum comfort. My second day of wear I wore the boots on a trail hike, with no adverse effects. The boots neither slide up or down, preventing irritation or undue compression on the heel.
