11．Children grow quickly，especially their feet．But many families cannot buy shoes each time a child needs them．As a result，about 300 million children around the world go without shoes．Those children risk picking up diseases and parasites （寄生蟲(chóng)） from the soil．
An American man may have a solution for those kids a shoe that grows with the child．Kenton Lee is the creator of the shoe that grows．He says，"The shoe can grow in the front； it can also grow on the side with Velcro fastener and on the back a buckle （鎖扣）．It can last up to five years．The bottom is compressed （壓縮的） rubber like what is used for a tire．The top is high-quality leather．"The shoes come in two sizes：small ones that fit children aged 4 to 9 and large ones for children aged 9to 14．
Lee says he got the idea for the shoe while working as a volunteer in an orphanage （孤兒院） in Kenya．He says，"There was a little girl in a white dress walking next to me．And I just remember looking down and seeing how small her shoes were．They were so small for her feet that she had to cut open the front of her shoes to let her toes stick out．And I just remember thinking，‘Wouldn't it be nice if there were a pair of shoes that could grow with her？'"
However，Lee says it was not easy to turn his idea into a reality．"The real reason why it was important for me to try to make the shoes that could grow was to help．So I made a promise to myself．"
In 2009Lee founded a non-profit organization called Because International．In the office of Because International，Lee kept a pair of his own shoes to help him remember his promise．"I told myself I would not get new shoes until the idea was done．So，those are the shoes that I wore for a little over five years．But once we finally made the shoe that grows，then I got some new shoes．"
