I put these bad boys through the paces in the mountains with a foot of snow for hours n hours. Not once did my feet get wet or cold. In the military Ive gone thru many boots, n also boots for motorcycle riding, and these docs didn't disappoint. They really took care of me n the lite soles kind of make you want to walk I cnt explain it. I cnt tell you they won't fall apart in time, but as a pair of docs they feel like there for life! Better then described thank you!
