These are used Simms Freestone Felt Sole Wading Boots, men's Size 9.
I wore them less than two dozen times. These regularly sell new for $120+, but take a good two seasons to break in (the leather is stiff but softens with wear). These ones are broken in nicely and still in good shape.
One of the soles is coming off, so you'll want to re-sole them. Simms will do the resoling at a reasonable cost. https://www.simmsfishing.com/repairs-landing
Or, if you don't want to deal with shipping, this guy in Seattle is recommended by Simms to do the repair work. http://www.davepagecobbler.com
(If you don't like felt soles, he'll put rubber Vibram soles on them for you!)
Great boots at a great price.
