Trimming your toenails using a long handled file after bathing, when they are softer, can make them easier to manage independently.
If you struggle or you have foot problems that you cannot manage yourself, a podiatrist or chiropodist can help. This is especially important if you have diabetes.
Try to wear footwear that protects and supports your feet with non-slip soles that are not too thick. Avoid high heels or backless footwear as they are more likely to cause you to trip.
