Very common with adolescent girls that play middle school and high school sports. More common with girls who play sports that participate in soccer, field hockey, lacrosse, and swimming. Most usually worn before or after a game and sometimes during school.
It is also quite common to be worn by adolescent girls that attend catholic school, while in their uniform, when they are traveling to and from school, by car or public transportation or walking, or after school at a public place such as a fast food place or the mall.
The three malls in the Philadelphia Area where you will find most catholic school girls wearing Adidas Sandals after school are Franklin Mills, Deptford Mall, and Moorestown Mall.
Most catholic school girls that wear these usually put their adidas sandals in their lockers during school. It is uncommon for unattractive girls to wear them.
A lot of men, 20 years old and older, who have a fetish for adolescent girls and their feet or who have a catholic school girl fetish, often find this very attractive and arousing. Some girls that attend catholic schools that require them to wear tights with their uniform, notably St Hubert Catholic High School For Girls, will wear socks under their tights for the reason that they do not want their feet to stink or because they do not want other guys to see their feet or toes. The term for this is often called "Hubert Denied" and is often used in conversation by guys, who share the same interests, who are disappointed or angry when they thought they could see the girl's feet through her brown St Hubert tights when later all they saw was an outline of her foot in a sock.
Also very common to be worn, with or without socks, by girls between the ages of 18 and 21, attending college while at their dorm or going to, from, anr/or attending class.
