QuiksilverMen's Molokai Marled Beach & Pool Shoes

I have foot size for shoe: "us 10 / uk 9.5 / eu 43". which size should i buy?

i got a size 12, the length is ok, but the straps are too tight.. if i get a size 13, will the straps will be looser, or will the shoe just be longer?

I’m size 7 us men’s... is there no size for me??

I’m a size 9 (us) what size should i choose? i don’t understand the chart :(
