These are fairly light duty boots. The leather is treated so they have quite a new smell. Not a problem since it will dissipate. The interior leather has a specialized cloth lining to increase "coolness", and the foot bed has air channels to prevent hot feet. For me I found the fit on the left foot perfect and the fit on the right too tight. The shoe in a 15 is very snug fit compared to say a "Keen" or "Merrel". The foot goes to a tapered toe so not ideal for me. On the other hand it is a very light boot, not a overly rigid or over sized sole. They definitely not a "work" shoe like the Keen version which is a beast. I say good for kicking around, everyday use.
