Watch Where You Walk
While padding around in sandals is a great idea, open-air footwear isn't suited for all terrains. In particular, avoid wearing sandals in the city, where the sidewalks may be covered with bacteria that could enter your injured toe, or on uneven ground, where an open toe is more vulnerable to bumps and cuts. Wear sandals around your home, but choose shoes with closed toes for urban or cross-country excursions. Also, be careful to not stub your toe, as that can produce injuries that cause the nail to thicken or grow inward.
