Professionally, there's no best shoe. But I can help you to decide the best shoes for boys and girls based on opinion.
Girls
if you're going for style, I would totally say Ugg boots or "Fuggs", a combination of the words fake and Uggs if you can't afford to buy a real pair. They're comfortable, cute, and can last through the snow. During summer, your best choice in shoe would probably be flip flops or tennis shoes depending on the event. (Tip: if you get tennis shoes, make sure they're stylish ;D )
Boys
most boys I know are tennis shoes people. Who could really blame them? They look the best on boys, athletes or not and are comfortable for a boys running around. During the summer, the best option would be "manly" sandals or flip flops. And they can wear their favorite pair of tennis shoes during hiking.
Like I said, there's no such thing professionally as "the best shoe". I gave the best for boys and girls based on opinion, so I'm not talking professionally or anything.
Nike Is The Best Shoe That You Can Play In!
The best kind of running shoe is anything by Nike. They are the best.
The best shoe ever is called Air Jordan. They are comfortable and everyone has them
The kobe 9 elite showtime is the best kobe 9 shoe
clarks,office and shoe zone
asics are great and nike makes a quality shoe
your shoe
Converse.
None is the best. It depends on your opinion.
I think the best signature shoe names are monsters fly and your last name and air and your last name.
It is really a subjective issue. There is no one best bare foot running shoe that is best for everyone. It depends on what you are looking for in the shoe. there is a useful video reviewing this type of shoe at http://www.fitsugar.com/Best-Barefoot-Running-Shoes-Reviewed-23631928
The best way to promote shoes is to have commercials and to have signs promoting the shoe and have people saying that this shoe is great on blogs.
