whats a good pair of shoes to workout in?

im running for 20 mins. then doing tybow im wearing nikes,cross training shoes, they felt good at first but not so much now.

A good pair of Asiacs. They have gel cushioning and are really comfortable. Saucony is another really good brand.

It's not so much the brand, but how it fits your foot. Some people are "overpronators", some "underpronators", etc. A great way to get a pair of shoes that actually fits your feet for running is to go to a specialty running store. Tell them you need shoes, give them your price range, and they will fit you with shoes for YOUR foot and the way your foot MOVES. General athletic superstores rarely do this. After you have been fitted, then it may be ok to go and purchase shoes on your own. I run in a brand I would have never guessed to pick out for running: Adidas. Just because they make a model that fits my foot and movement very well.
Nike Airmax 180s or Asics either one are great running shoes. Get something that has support and is light weight!
