Some styles will need to have the upper made with a thin, abrasion-resistant stretch polyamide fabric. Other styles will need the upper to be made with a soft, tear resistant leather. The bottom should be made from a performance rubber compound, and should be non-marking and provide excellent grip and ground feel in both wet and dry conditions. They should be machine washable with liquid or powdered detergent. I need 3 men styles and 3 women styles. I will start with an initial order of 30 per style, making the total order size 180 pieces. After this initial order, I will increase my order size to 50 per style, then 100 per style, up to 200 per style and possibly much more depending on US national distribution. Show More
