I sized up to a 9.5 which is listed as an EU 41, but probably could have gotten away with an EU 40 / US 9. The toe box is cut nice and wide. Stitching feels solid and fabric has not warped yet. The soles are a similar foam plastic to popular molded clogs or shower sandals, so these are definitely more of a fashion shoe, not the shoe to look to for traction or for long term heavy wear & tear. I get compliments on them consistently, and they are comfortable, but next time I'd order my true size, and make sure they're not my "main" sneakers for walks/working out, as I anticipate needing to replace these within a year.
