Can I have some suggestions for somewhat cute flip flops/san

Birks work for me.

Reef sandals also have been supportive

I'll say in advance that I think everyone has different needs depending on what the structural issue is (flat feet vs high arches). Fit Flops have been the best for me. Changed my life honestly. I wear their flip flop type shoes, sneakers and boots.

I have a rec for one of each - true flip flip: Archie's (from Australia) and a Havaiana's slide (from Brazil). Have walked miles unplanned in each, including in the rain, mud, and forest trails.

I just bought some Skechers Slip-in ones that are super comfy too. Your best bet is to try on a whole bunch to find which feel best for you!

These look decent, are very comfortable, and have clinical arch support. PowerStep Archwear Women's Arch Supporting Thong Sandal.

I think birks are cute! They're my go to summer sandal
