Are these men’s or women’s shoes and sizes

These shoes are women’s sizes. I always go down a size in all the Crocs styles because they tend to run big. These are also my favorite Crocs style because they look and stay on your feet like regular shoes. They are extremely comfortable. I hope this helps you!

For half sizes, do they run big? I wear 7.5 don’t know if I should order up or down

I normally wear a size 8 medium in all my shoes. The Crocs shoes are the exception. I went to the Crocs show store and tried this style on and I had to downsize a whole size. Actually I buy a a size 7 medium in all the Crocs styles. For you I would recommend the size 7 medium. As far as I know all the Crocs shoes come in a medium and do not come in half sizes. Amazon has outstanding customer service, in the event that you would have to send them back. They are also $10.00 cheaper on Amazon, than on the Crocs website. I hope this helps you!
