I have a pair of metal squat shoes that have been used for ~8 weeks. I took them off between sets so they're in great condition with no signs of wear. The label inside the shoes mislabels them as 9's but they're probably around an 11 since I wear 11-11.5 and these fit me snugly. They really tear up the ground and offer a lot of stability. If you're looking for a flat shoe with a metatarsal strap and a very thin sole for deadlifts then this might be your best option. These shoes are kind of rare nowadays and hard to find on the secondary market. I bought them for over $200 and will take $100 for them. Again, they're in near perfect condition.
This is not my pic but they look like this:
Too small for my feet but they look like great shoes. I'll ask some of my friends.
