I bought these new from Sportman's Warehouse not long ago for $30 even though I thought they might have been a size too big (heard they run small). Tried them on, put them in the water, and realized they are way too big for me once they get wet. My loss is your gain if you have bigger feet than me.
If interested, send me a message through the Craigslist mail relay system. Pick-up will be in the City of Wausau either in the downtown area where I live or on the north side of town where I work. Thanks for looking!
