Hello, for a year-ish now, my big toenail's had weird, white spots/marks on it, and the part of the nail not attached to the nail bed has a brittle texture. I don't use nail polish, and I wear socks every hour of the day, even sleeping. I tried clipping my nails to get rid of the white spots, but they came back when the nail grew again. It's only on the big toenail.
I tried doing research on it, and my nail is not yellowed, or thick, or peeling or breaking off. It's just a little brittle and with some white spots.
I will include pictures below:

If you push your cuticles back on those nails you can can cause damage to the nail bed and white spots and brittleness may occur.
Although you say the nails are not yellow, thick and peeling, it would be a good idea to use an antifungal preparation on them daily for a year or two to stop any form of fungal possibility. If you wear socks 24 hours a day you are highly likely to get a fungal infection. Try going barefoot or wearing open toe shoes whenever possible
PS Yes, I did mean a year or two to treat your nails. Once these infections set in they can be very difficult to get rid of and treatment is usually ongoing..
