Shoes... Help

32 weeks pregnant, I am a cosmetologist so I'm on my feet while working. Luckily I only work part time now. 
Anyways I have comfy keen sandals but my feet are starting to swell up more now the more I stand, so I've just been wearing flip flops. But these are terrible too and I go home with sore feet and back/hip pains. Ugh!
Are there any comfy supportive flip flops out there? Anything that won't cut into my feet? Helppppp.
