I got these boots for my 16 year old son who is in a police program and does a lot of running/PT in these boots. He loved them from the first time that he put them on. Says they are so comfortable that he wants to get another pair to wear full time. He also said that when he ran in them they were more comfortable than the tennis shoes that he was running in before, and he loved the tennis shoes. They seem well made. The zipper is really nice.
