Here are a few tips from Dr. Brandon Nelson and Dr. Timothy Young from Issaquah Foot and Ankle Specialists:
Choose appropriate footwear – If you are active and participate in sports select footwear designed for that specific type of activity. A toe box appropriate for your foot structure is important preventing ingrown toenails and other injuries. Shoes that you wear every day should have plenty of room around your toes. Shoes that you wear for walking briskly or for running should have plenty of room also, but not be too loose.
Check your toes – Ingrown toenails can often be avoided if you take care of your feet. Take a moment to examine your feet and look for signs of ingrown toenails. If you notice any red, swollen and painful areas of your toes near your nail you should have it evaluated.
