I read the reviews about Belleville boots being known for their comfort so I thought I'd give the 700 ST a try. I have flat feet which has led to problems with planar fasciatis so I experience a lot of arch pain. I have special orthotics and they fit well in these boots. I'm not gonna say they're the best boots in the world but I haven't had any problems and it greatly reduced the pain in my arches because of the good support it provides. They were pricey but I haven't found a sub $100 pair of boots that have been this comfortable.
i've had $250 danners that haven't been as comfortable as these. great boots. you can really tell the difference after a 10 hour shift with these boots on.
