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?

What Weight are these sandals?

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.
