I wear a 10.5 in sneakers but for some reason i'm a 10 in shoes. I chose these for summer time so will wear them with no socks. They fit good but aren't super tight. the inside is completely soft and padded so wearing no socks will be fine without having to worry about my feet being rubbed/cut up. I do recommend that you scotchguard them because of the light color and material. I have a feeling they will show stains easily. (the color in the photo is pretty spot on)
