德国采购需求：鞋类制造商、包袋制造商、自有品牌鞋类、自有品牌包袋、定制女鞋、鞋匠

I'm interested in partnering with your factory to create a custom line of sneakers. I'd love to explore the possibility of designing my own unique styles and would appreciate any information you can provide regarding your production capabilities for custom footwear. Could you let me know about the minimum order quantities, available materials, and any specific design requirements? Additionally, I'm curious about lead times and potential costs. Looking forward to your response!
