Nike, its more popular
theyre made by underarmor
Most name brand shoe companies such as Underarmor offer great lightweight shoes for running. Go to you local sporting good store and try out Underarmor running shoes. I've gotten great performance out of Nike Lunaracers as well.
It depends what position you play if you are a striker(forward) i would recommend Adidas F50's or Nike vapor's. Midfield i would recommend Adidas Adipures or something in that area. Defense and keeper any power cleats preferably puma.
There are a number of popular brands of nurse shoes on the market today. It is important that shoes are comfortable to wear during the long 12 hour shifts. Nursemates, Earth Origin, Nike Reax, Dansko and Birkenstock are some of the better brands.

Apart from Nike you have Puma and Adidas.
Nike is a huge one. Nike shoes were named after the Goddess of Victory, Nike.
Nike shoes may be more expensive that other brands, but they are also a better quality. The best thing to compare prices is to go to a store that carries this brand.
I don't think merrel running shoes are as good as nike. You can go to eastbay and compare brands of all types of runnin shoes to have a better idea of what the differences are.
Nike. Jordan.airmaxes.addidas. Etc
Depends on if they have personal endorsements and advertising rights, and what team they play for. It can vary between Mizuno (my personal favorite), Underarmor, Nike, Addidas, Reebok, Rawlings.
Nike, Puma, and Adidas's my favorite is Nike plus Nike brand lasts the longest so It is probably Nike but Puma and Adidas are nice too.
