Seems to even be the case within the same style. After two pairs of the black/white 9.5 CTAS (one high, one low) fit perfectly, my newer pair of all black 9.5 CTAS (low) are too snug. I can do them with thin socks, but they’re really noticeably narrower around the ball of the feet.
(I’m a tts 10.5 too.)
You’d think that people constantly commenting on the narrow fit and sizing issues would lead companies like Converse and Adidas to like...fix those issues...
