I have had very good luck with CL selling, for items over $60 in value.
Example, This year I have sold a cooler, tent, construction materials, snowboard boots, tent awning, trombone, violin, etc. "durable" items sell well. Heck, I even sold a 2 year old toilet on CL before!
I have people come to my home, as it is easier, although i have met others in parking lots to buy from them. Most will negotiate at least a little bit, but if you have the lowest price on CL, sometimes no bargaining -- they just want to check it out.
Price it right (30-60% of the original price).
Price boots quite low--20% to 30% original full price. they will require a lot of time / people showing up unless you price them very low. Be certain to post the shoe size and pics of any damage. BUT, if they are work or hiking boots, they should sell on CL. I tried to buy hiking boots on CL, and it is SUCH a pain to buy boots this way, that the price has to be very, very low for me to drive somewhere to check to see if the condition and fit is right.
Expensive Sporting equipment is especially good on CL, try to time the season (skis in summer may not sell, for example). There may be a wave of people checking out CL after Black Friday, too.
Good Luck!
