ReebokUnisex's Nano X3 Sneaker

I am confused with the size list. Men/women sizes shown as the same number together. Which one should i consider for a size 10 men?

Size comparison nano x1 vs nano x3: i bought the nano x1 which are 29 cm. i'm looking to buy the naxo x3 with 29-30 cm. which size should i order for?

What size is a uk 8.5 please? the sizing chart is very confusing.

What size would 25cm be? There are so much difference among the different size tables found online.
