Have not had these long, however my initial thoughts are that these boots lack something from the ankle up,  in design or material,either way they are a little uncomfortable. I suspect for looks or to conserve a little material/padding ie. bulk ( see how narrow the boot gets from the ankle up) they have sacrificed on comfort. As for other aspects of this boot seems excellent.
Have had the boots for a little over a month now and they seem to be breaking in and getting a little more comfortable. The rubber part of the boot has developed creases and I hope this doesn't mean they are going to wear through there.
