Many people have a long 2nd toe. In runners, a long 2nd toe can cause repetitive trauma to the toenail, resulting in a thick, protruding toenail This happens especially when running down hills.
If you are a runner and your toenail looks thick like this, you will only make matters worse if you ignore it. Thick nails always have to be treated, otherwise your nails will become permanently deformed.
If your nails are thick, go straight to your nearest podiatrist and have them thinned. The procedure is painless and will make all the difference in appearance and comfort. Oh, and just in case you were wondering, the red in the above image is residual polish, not blood. The white appearing adjacent toenails have a surface type of fungus, primarily due to polish, and easily filed off.
