I'm looking for details on your range of safe rain boots, as we're exploring options for our upcoming inventory. Specifically, I need to know about the materials used, safety features, and any certifications related to slip resistance or waterproofing. It would also be great to get information on sizing, color choices, and any customization options available. Additionally, could you provide the pricing structure along with any bulk order discounts? I'd appreciate lead times for production and delivery as well. If there are existing client testimonials or reviews regarding the performance of these boots, that would also be helpful in making our decision. Looking forward to your detailed response!
