Cutting your toenail too short or rounding the edge of the nail can cause it to grow into the skin. Wearing shoes or socks that don't fit well can also cause an ingrown toenail. If your shoes are too tight, they might press the nail into the toe and cause it to grow into the skin. You can get an ingrown toenail if you hurt your toe, such as stubbing it. This can cause the nail to grow inward.
A rider can be of any height if he or she still can make the assigned weight, but it is generally limited to fairly short individuals because of the limits on a person's body. The average jockey has a light but athletic build, and body weight is anywhere between 108 to 118 pounds.
The maximum weight of a jockey, including full gear, saddle, and saddle cloth is 126 lbs. in a Triple Crown race. In some races it can not exceed 112 lbs.
