X-Large is about a size 12-13 shoe size foot USA.
Material Type: Black - 3 Pairs, Size: X-Large
I love them they work fantastic. I am a big guy with swollen feet. Wear size 12 to 13 USA Shoes. They fit me just fine not tight. My feet felt good after wearing them for two days. Some dry skin pulled off with them and it says to wash by hand. I dont know about the durability but I am hoping to get about 5 uses per pair. Before they become unusable.

Comfortable
Material Type: Black - 2 Pairs, Size: X-Large, Material Type: Black - 2 Pairs, Size: X-Large
I have very sensitive skin, so I usually need to wear socks at all times. These are especially comfortable because they don’t cover the toes, which helps with temperature control. The material is well-balanced—not too thick or too thin—and has just the right amount of stretch. I also appreciate the large traction area, which adds stability. Another plus is that they are completely fragrance-free.

Great Heel Socks
Material Type: Black - 3 Pairs, Size: Large
I don't know how they work but it's wonderful. I've had rough heel problems for a long time. I wear these everyday and my heels are not rough. They're not baby bottom smooth, but they are not ever going to be. These heel socks also oncce they are properly positioned snap onto the heel. Properly positioning them is easy when you put them on your foot with the heel cup in the correct orientation.

Too small
Material Type: Gray - 3 Pairs, Size: X-Large
Too tight! Even size large used for a man with smaller feet is too tight. Also, no instructions for use or care.
