They are a well made boot for sure. But I would recommend you head down to sportsman's warehouse and try them on first. Or if mail order wear them around the house for a while first to make sure of the fit.
I put a lot of miles and endless blisters on my heels before I finally gave up.
Everyone's foot is different so you may have nothing but a positive experience as many people do. For me it was an expensive error. I have nothing against them but I've moved on to Zamberlan and found a better fit.
