Not to my taste, but not distasteful either IMO. I think they would work with a summer suit with no tie maybe (not tan, maybe khaki green/grey/etc), probably fine with jeans.
Those loafers immediately above are truly awful. Did Bottega Veneta not sell enough bags last year, forcing the Gucci Group to use BV's surplus leather on some ugly shoes? But unexceptional Gucci loafers such as the pair in the OP are now five hundred five dollars? Damn. I thought they were somewhat overpriced when I bought mine for about half that. Sure it was 8-10 years ago, and they were some small percentage (maybe 20% or 30%) off, but that's some inflation.
