I'm looking for a quote on a specific type of safety footwear. I'm interested in brown Goodyear welt safety shoes made from cow leather, featuring a steel toe and midsole for added protection. The size I need is US 8. It's crucial that these shoes are durable and comfortable for long hours of wear, so any information on materials and construction methods would be appreciated. Additionally, please provide details regarding the shipping options available to El Salvador, including estimated delivery times and costs. It would also be helpful to know the minimum order quantity and any bulk pricing if applicable. Looking forward to your prompt response with the pricing and relevant details!
