8. Foot Bone Problems
Bouts of plantar fasciitis cause your body to produce additional bone to try to heal from the constant pulling. However, the additional bone turns into a heel spur located in the back or bottom of your heel. The heel spur causes additional pinching and pulling. The spur area becomes very painful and may need surgery to return it to normal.
7. Sole Puncture Risks
Flip flops do not afford much sole protection. A thin piece of rubber is all that stands between your foot and the ground. If you step on a nail or a tack, then it can easily penetrate the rubber and go directly into your foot.
As the object embeds into your foot, a piece of the rubber sole of the flip flop can also become stuck in the tissue. It is not uncommon to require surgery to remove the rubber from the bottom of your foot if it becomes stuck in the delicate skin. Also, you are at an increased risk of infection because of stepping on the object.
6. Toe Twisting
Flip flops twist easily. Your toes hold the shoes in place. However, to keep the shoes in place, your toes are constantly in a curled position. You might not even realize that you are curling your toes to hold the shoes in place. However, the curling can cause your toes to deform.
Over time, holding your shoes in place with your toes causes curled toes. The unnatural curvature leads to toe pain and foot cramping. Your toes start to bend upward too, and the unnatural position leads to all kinds of problems. The upward curve of the toe is referred to as hammertoe.Related: 10 Tips to Fix Flat Feet Related Health Issues
