Womens To Men's Sizing??

So I went to the store and tried some women's Rebel v4s. For the Women's Sizing, the best fit was US 7 (24 cm), however, since I'm planning to buy from online resellers, and if i'll buy the Men's version which uses the Male sizing table.

Now, to my confusion: Women's Sizing Table - 24 cm: US W 7 - US M 5.5 Men's Sizing Table - 24 cm: US W 7.5 - US M 6

Should I just stick with the centimeters to convert from Women's to Men's and order US M 6 (in Male sizing)??

Note: - Yes, from my country it is cheaper to buy from resellers doing pre-orders from Japan/Taiwan sale. - I also need wide shoes so Men's 2E is wider than Women' D (i assume, which is very preferable in my case)
