Affordable sneaker recommendations?

Hey guys! I've recently outgrown my old Nike sneakers and need new sneaker recommendations that are good for working out. I find that I get pain in the arch of my foot and the outer side of my lower legs/side of my ankles when I do jumping exercises. I have a relatively flat arch in my foot so I need something that can suit that too. I've been looking all over and a lot of the sneakers I like are over my budget. If you guys have any recommendations for shoes $50 or under that would be great!
