Shoe Recommendations

Hi FB community! I am a preschool teacher and spend 10 hour days mostly on my feet. I find that by the end of the day my feet are often extremely sore and occasionally have soreness in my knee as well. I have been wearing converse sneakers to work but am thinking that I should probably invest in something with a bit more support to prevent end-of-day soreness. Any suggestions? I am in need of new workout shoes too, so if you had any ideas that could double for both purposes that would be great too! Thanks!
