MarugoTabi Action Shoes Split Toe Breathable Sneakers Sports Jog II

Selecting 11.5 mens size changes to 11 size right at checkout. How do i make sure the size i want is actually ordered?.

Are the soles (oil) slip resistant?

Are these the same sizing as with the marugo hitoe? A size 6us for the hitoe fits me just right. I would like to find the right sizing before I order.

If I wear a 7.5 men’s in normal shoes what size should I get these in?
