Very rugged boot. Fits great for those with narrow feet. I have worn these for over a year now and they are great. No water is getting through these and they are great for carrying loads over 20 lbs. The interior of the boot is seamless and mold in such a fashion that they almost suction on to your feet. I have gone miles with one of them accidentally being unlaced and didn't even notice.
Not so good for light hiking. Something more flexible would be better for that.
