TevaMen's M Hurricane XLT2 Sport Sandals

I want a size 6 uk. when i enter that in the size box, it accepts it, but when it goes in the basket the size shows as 6 us. will i get uk or us size?

The images of the rapids insignia blue version appear vastly different here than on toad footwear website. different version or poor photographs?

I really want these sandals, but ordered uk6 and was sent us6. how do i get the correct size? i'm returning the wrong size sandals.

Are they true to size? I am a large size 8
