Proper toenail trimming is essential for foot health. For years, like many, I cut mine in a semicircle—but this is a common cause of ingrown toenails, which are incredibly painful.
Thankfully, my podiatrist shared a simple, effective method. Since using it, I've avoided ingrown nails entirely.
The secret? Trim them into a square shape, not rounded. See how:

1. Disinfect your nail scissors with 70° alcohol.
2. Use a marker to draw a straight line across the nail where it emerges from the skin, from one side to the other.

3. Shape the nail to form right angles at the corners.

4. Cut straight along the marked line with your scissors.

5. Repeat for all toenails.

That's it—you now have perfectly trimmed toenails, done quickly and easily! This method excels at preventing ingrown toenails, especially on the big toe, a frequent issue for walkers and athletes.
Ingrown nails hurt and can lead to infections like mycosis. Key takeaway: Keep toenails square, unlike fingernails. It may look less polished, but it stops nails from digging into skin—even with prominent edges—so you can walk and run pain-free.
- Trim after bathing or showering when nails are softer.
- Work in bright light and wear reading glasses if needed.
- Nail scissors are ideal and readily available. For thick nails, a clipper works but scissors give straighter cuts.
- Avoid crushing cuticles to prevent infection.
- Use a blunt-tipped tool to clean under nails.
- Choose wide shoes that don't squeeze toes; opt for open styles or barefoot when possible.
- Wear breathable cotton socks and maintain foot hygiene.
This creates a 90° angle that protrudes slightly from the toe edge, preventing the nail from embedding into flesh and causing injury or infection.
If bending or cutting is difficult—due to mobility, pregnancy, or thick nails—ask for help or see a podiatrist.
