Saltwater sandals sizing help! (with photo)

[BusyBea]

I've bought a pair of Saltwaters from Office in a size 6. My left foot is more of a 5.5 and is narrower than my right. They are pretty roomy on my left foot and I'm worried about them stretching as I've read about this happening. I'm not sure if the length would be too short on my right foot if I swapped them for the smaller size.

I've attached a pic to show what I mean. Should I worry about the leather stretching or do you think it will be ok?

I must have a weird unbalanced body because I've had to fasten the left foot two holes tighter than the right

They should be ok, they will only stretch to the shape of your foot

Thank you. I will keep them and see how I get on
