FITORYWomens Flat Sandals Fashion Round Open Toe Slip On Slides with Braided Strap Slippers for Summer Size 6-11

Unsure if i should get a size 8 or 9. Usually 9 is too long 8 or 8.5 fit but i have a wide foot. Will an 8 fit ? Is it a loose fit sandal

I wear a size 6.5 which size should I order?

I'm confused . My foot measures 9 inches, what size should I choose?

Are these flexible or bendable when you walk?
