How should the corners of toenails be shaped for optimal results?

Shaping the corners of toenails in a rounded fashion is ideal for optimal results because it helps prevent ingrown toenails. When the corners of the nails are squared off, they can grow into the surrounding skin as the toenail grows, leading to discomfort, pain, and potential infection. A rounded shape allows for a smoother contour, which reduces the likelihood of the nail edges becoming embedded in the flesh. This shape also provides a more natural and aesthetically pleasing appearance, enhancing the overall look of the pedicure.

While other shapes like square, uneven, or flat can be aesthetically appealing in certain contexts, they do not offer the same health benefits and risk mitigation that a rounded shape does, particularly for toenails that are more susceptible to pressure and friction inside footwear.
