Old Stock
We've recently refined our production so that all newly-made pairs feature pitched heels (on leather-soled styles) and higher density stitching (on all styles). Old stock is simply any pair produced prior to us making these changes, so old stock does not enjoy these details.
We still have a large amount of such "old stock" inventory, so we're clearing it out. Enjoy 40% off on these pairs: Our loss is your gain!
