SF members, I have a question. I've been trying to sell a pair of new JL Chambord II Derbies and I'm having trouble understanding the lack of interest in them. I'm pretty sure my current price is extremely competitive, so perhaps the size (11 E UK) is an issue, or maybe style, or is it something against spending a lot on rubber bottom shoes even though they are JL's. Is $550 a great price for new Lobb's? Thanks.
