I need new slippers! will be very well worn, wide feet, mule recommendations please

[MaybeItsTimeForMeNow]

As title says... I'm a 6.5, wide feet, although I appreciate a lot of slippers give after a while. Mule style please. I'm a WFH-er so they will be well worn so bonus if they have additional support. Budget up to £40 max.

Thanks so much

Bit more than £40 but I wear Josef Siebel's Betsy Clog as indoor shoes/slippers. They have arch support. Purchased the last pair in 2021 and have at least another four years in them so on a cpw basis vfm.
