Swollen feet.. cankles...shoe recommendations?

Jillian

Hello ladies! My piggies are starting to get swollen! I'm still working for another 4 weeks... In a hot school with no AC! Lots of walking around as a teacher! Any suggestions for comfy shoes? I can wear sneakers if I get a doctor's note.. but I'm thinking it will be too hot soon!

Flip flops are digging in!

Suggestions welcomed! TIA!
