How on earth would you keep these shoes clean?

[mostlymindblown]

I quite like the look of these

but they are nude suede so I assume would mark really easily...

There seem to be loads of cream/nude/pale pink suede type shoes in the shops at the moment and I think they look lush but would they just get filthy in no time even using protection spray etc?

Often the ones to try on have already got scuffs and marks on them so that doesn't give me much hope. Or are there some special light shoe cleaning / protecting tips that I am not (yet ) aware of?
