Hi, I would like to ask the shoe experts some advice. Im planning to buy some van Bommel's (Dutch upscale shoe maker), they're an older (ladies) model and not available at the stores anymore. Im a bit squeamish about used shoes but I really like this model and since they're in my size... Seller wants 40 euro's for them. They still have the original soles but they're not that clean anymore. Do you think they're worth the price she asks? Thank you!
