These are my 2nd pair of Frye boots and they are well worth the money.  More comfortable than Doc Martens ever thought about being, especially since Docs are made in China now.
These Frye boots are super soft with a great arch and flexible, yet sturdy construction.
The leather softens up after a few wears for a nearly custom fit.  They run a little narrow so if you want to wear thick socks, go up a half size.  I also have the Frye harness boot with the 12 inch shaft and the color and comfort just keep getting better and better over the years.  Well worth the investment.
