Yeah I actually emailed a sales rep about them, seems like they are hard to get your hands on. 2 things are drawing me to them...the fact they have built in creepers in the heel and their other models of cold weather boots claim to be 30-40% lighter than their competitors. Based on that I think they would be a lot easier on the body (particularly because I walk everywhere I fish) than my Mickey Mouse boots. My father in law says the rubber always cracks on those styles of boots though
