Prada mens driving shoe, blue/silver leather

Mens driving shoes from Prada, size is listed as "9" but it's a European size, in the US, I wear a 10.5/11. Navy blue with silver fabric and red accent, this Driving Shoe style has a very thin sole and rubber inserts on the bottom and rear heal for traction. Bought from Neiman Marcus, they were just under $500. We recently moved from the (cold) NE and moved to Florida, so we're getting rid of our winter clothes and our formal and business clothes (only suits we need are bathing suits!). All the items in our closet were personally purchased by us at either the brands boutique, or a large retailer like Neiman Marcus or Saks. EVERYTHING is 100% authentic and genuine! We have no kids, no pets, smoke free home.
