CrocsUnisex Adult Crocband Flip Flops

anybody have a problem with straps that are really loose

What material is between the toes?

Im 40 in eu should i buy the size 8 d (m). in the croc site looking for the relaxed fit

Are some colors softer? After much experimentation, I've found the white color much softer, but the last white pair were firm like the rest.
