Superfit
Barefoot brand from Austria.
Superfit is an Austrian children's shoe brand with a barefoot range called barefit, which I'd count as a mainstream brand dipping into barefoot. The barefit shoes include SUPERFREE and FLUMMI first walker styles, plus boots, sandals and indoor slippers, with thin flexible soles, an asymmetrical last with room for little toes, and soft leather. They still make plenty of conventional kids' shoes too, so check you are looking at the barefit ones.

How Superfit fits
sloped toe box, multiple width, medium volume
Superfit's barefoot shoes are children's sizes only, so there's no adult fit to report. A retailer notes the Superfree tapers slightly at the big toe and is narrower at the heel, so use the insole fitting line and check which width you're buying.
