Hi all,

I’m trying to figure out sizing for the Clifton 10 and got a bit confused compared to my current pair.

I currently wear Clifton 9 (women’s) in:
US 7B / UK 5.5 / EU 38 2/3 / JP 240

They fit me well. My foot length is ~242 mm, and I have about half a thumb width of space in the toe box.

I usually rely on JP sizing, but in Clifton 10 the sizing seems to have shifted:

• US 7B = UK 5 = EU 38 = JP 235
• US 7.5B = UK 5.5 = EU 38 2/3 = JP 240

So what used to be US 7 is now US 7.5 for the same UK/EU/JP size.

Question:

Should I stick with JP 240 (now US 7.5) to get the same fit,

or

Could US 7 (JP 235) still work because of the updated shape (roomier toe box, different geometry, higher drop)?

Would really appreciate any real-world feedback, especially from people who moved from Clifton 9 to 10.

Thanks!
