barefoot mean less fungal infections and less foot ming if you did it more. Main foot ming comes from shoving feet in sweaty stale shoes and socks for hours upon end where they bath in their own fetid sweat juices.
Walk around a lot in barefoot, been into supermarkets, pubs and shops no problems (although the security guard did used to follow me in the supermarket?) will probably do so a lot this summer, just winter is a tad cold.
Also barefoot or totteringly massive high heels, I know which look more accident prone to me. Probably more likely to slip in bike shoes than barefoot.
I also took up running barefoot a bit up until the snow so maybe I am not the best person to be putting my opinion forward.
